The Round Tower, Windsor Castle

I. Introduction

Towering over Windsor Castle’s sprawling complex, the Round Tower stands as a sentinel, a silent witness to centuries of British history. Its imposing form, a sturdy stone cylinder, embodies the castle’s enduring legacy as a royal fortress and residence. For over 800 years, the Round Tower has played many roles—a formidable defensive stronghold, a luxurious royal residence, and even a temporary prison.

Its presence evokes a sense of power and grandeur, a tangible reminder of the monarchs who have walked its halls and shaped the nation’s destiny.

Originally constructed in the 12th Century by King Henry II, the Round Tower served a crucial purpose – to fortify Windsor Castle against potential invaders. Its circular design, thick walls, and elevated position offered a significant advantage during medieval warfare. Cannons were mounted on its battlements, ready to repel any attackers.

However, as the threat of war receded over the centuries, the Round Tower’s role shifted. Monarchs found its lofty chambers and panoramic views desirable, offering security and a sense of grandeur. The tower’s interior was adapted for royal living, with comfortable apartments and luxurious furnishings. For a brief period, the Round Tower even served as a prison for a few notable figures.

Today, the tower is a celebrated landmark, welcoming visitors worldwide to explore its rich history and breathtaking views. The “Conquer the Tower” tour offers a chance to climb the 200 steps to the top and be rewarded with panoramic vistas of the castle grounds, the Thames Valley, and even the distant skyline of London on a clear day.

II. A Storied Past:  The History of the Round Tower

A. A Legacy Built by Henry II

1. Architectural Innovation for Defensive Prowess:

The Round Tower’s design reflected the prevailing military architecture of the Norman period. It adopted a circular form, a significant departure from the rectangular keeps that were more common earlier. This circular design offered several advantages:

• Superior Defense: Curved walls were less susceptible to damage from siege engines like battering rams, which relied on concentrated force on a single point.
• Eliminating Weak Points: The absence of corners eliminated weak points that could be exploited by attackers attempting to scale the walls or tunnel beneath them.

2. Strength and Durability in Every Detail:

Constructed from a type of local limestone known as Kentish ragstone, renowned for its strength and durability, the Round Tower stood as a formidable obstacle. The walls were incredibly thick, reaching a staggering 15 feet at the base, creating an impenetrable barrier.

3. Defensive Features for a Multi-Layered Approach:

• Crenellated Parapet: At the top of the tower, a crenellated parapet with evenly spaced merlons (the raised sections) and crenels (the gaps) provided a defensive platform for archers and soldiers.
• Machicolations: Openings beneath the parapet, known as machicolations, allowed defenders to drop projectiles and missiles directly onto attackers attempting to scale the walls.

4. The Round Tower as Part of a Cohesive Defense System:

The Round Tower wasn’t solely a standalone structure. It served as the central keep of Windsor Castle, forming an integral part of the overall defensive scheme.

• Curtain Walls and Gateways: A series of curtain walls, fortified with additional towers and gateways, extended outwards from the base of the Round Tower, creating an enclosed courtyard or ward.
• Concentric Defense: This layout created a concentric defence system where attackers would have to breach multiple layers of fortification before reaching the castle’s heart.
• Ultimate Stronghold: The Round Tower, positioned at the highest point within the complex, served as the ultimate stronghold, a place of last resort during a siege.

B. Transformations Through Time

1. Early Modifications (12th & 13th Centuries):

Gateway Addition (King John, 1199-1216): A few decades after its construction, King John made some alterations to the Round Tower. He added a gateway at the base, allowing easier access to the upper floors. This gateway was later blocked up and replaced with a new entrance on a higher level during subsequent renovations.

A central shaft was also constructed within the tower, providing access to the various floors.

2. Shifting Roles (14th Century):

As the threat of warfare diminished over time, the Round Tower gradually transitioned from a purely military structure to a more versatile space. Monarchs began to appreciate the tower’s elevated position and spacious chambers, finding them suitable for royal accommodation.

Edward III’s Renovations (1327-1377): In the 14th Century, under the reign of Edward III, the tower’s interior underwent significant modifications to adapt it for royal usage. Windows were enlarged for natural light, and some chambers were decorated with fireplaces and ornate plasterwork. Edward III’s son, John of Gaunt (1340-1399), used the tower as his primary residence.

3. Impact of Historical Events (15th Century):

Wars of the Roses (1455-1485): During the Wars of the Roses, a period of civil war between rival royal houses, Windsor Castle, and consequently the Round Tower, briefly fell under the control of the Yorkist faction. This highlights the tower’s vulnerability during prolonged conflict despite its formidable defences.

However, the castle’s strategic importance remained paramount, particularly due to its proximity to London. The Lancastrians quickly recaptured Windsor, demonstrating the tower’s role as a vital asset in controlling the region and securing a strategic advantage during the conflict. This episode underscores the Round Tower’s dual purpose: as a defensive stronghold and a symbol of power for the reigning monarch.

4. Transformations under the Tudors (16th Century):

Tudor Architectural Trends: The Tudor dynasty (1485-1603) ushered in a new era of architectural trends. While the Round Tower wasn’t significantly altered structurally, it continued to be used as a royal residence, particularly for visiting dignitaries. King Henry VIII (1491-1547) embarked on renovations at Windsor Castle, aiming to create a more palatial residence. The Round Tower, with its strategic location and historical significance, likely remained a prestigious space for guests of the crown.

5. Later Adaptations and Modernization (17th Century – Present):

The English Civil War (1642-1651) saw Parliamentary forces besiege Windsor Castle. While the Round Tower wasn’t directly involved in the conflict, it likely served as a secure storage space for valuables during this period. Following the restoration of the monarchy, the tower’s use primarily shifted towards storage and administrative functions.

In the 19th Century, a renewed interest in medieval history led to efforts to preserve and restore Windsor Castle. The Round Tower benefitted from these endeavours, undergoing renovations that aimed to maintain its structural integrity and historical character.

C. Notable Residents and Captives

1. Kings and queens who used the tower as a residence:

• Edward III (1327-1377): As mentioned earlier, Edward III played a crucial role in transforming the Round Tower into a more comfortable royal residence. He likely spent time within the tower, enjoying the panoramic views and spacious chambers.
• John of Gaunt (1340-1399):  Edward III’s son, John of Gaunt, the Duke of Lancaster, famously used the Round Tower as his primary residence for a significant period. He likely oversaw further modifications to enhance its suitability for a nobleman’s lifestyle.
• Henry VIII (1491-1547): While the Round Tower wasn’t Henry VIII’s primary residence, he did use it occasionally, particularly for housing visiting dignitaries. The tower offered a prestigious and secure space for the crown’s guests.

2. Famous historical figures who were imprisoned within its walls:

• King John of Scotland (1242-1296):  Following his capture by English forces in 1296, King John of Scotland was briefly imprisoned within the Round Tower before being transferred to another location. His incarceration served as a symbol of English dominance over Scotland at the time.
• Charles, Duke of Orléans (1394-1465):  Captured at the Battle of Agincourt in 1415, Charles, Duke of Orléans, spent over two decades as a prisoner in England. While not exclusively confined to the Round Tower, historical records suggest he spent some time within its walls. Charles became a prolific poet during captivity, and some of his most famous works were likely penned in the tower’s chambers.
• Henry, Duke of Gloucester (1448-1447):  A controversial figure in English history, Henry, Duke of Gloucester, was the younger brother of King Henry VI. Accused of treason, he was imprisoned in the Round Tower in 1447 and found dead shortly after that under mysterious circumstances. His death remains a subject of historical debate.

3. Accounts and Legends Surrounding Residents:

While historical records provide details about some of the Round Tower’s notable residents, captivating stories and legends have also emerged surrounding their stays.

a. John of Gaunt and the “Queen’s Apartments”:

Legend suggests that John of Gaunt commissioned the construction of a set of luxurious apartments within the Round Tower specifically for his wife, Katherine of Lancaster. These so-called “Queen’s Apartments” were supposedly adorned with tapestries, rich furnishings, and even a private garden on the roof. However, concrete evidence for these elaborate additions needs to be included.

b. The Ghost of King John:

Perhaps fueled by the dramatic circumstances of his imprisonment, stories persist about the ghost of King John of Scotland haunting the Round Tower. These tales often depict him as a restless spirit, wandering the halls and lamenting his captivity. Visitors and staff have reported unexplained sounds, such as footsteps and mournful sighs, emanating from supposedly empty tower sections. Some even claim to have glimpsed a shadowy figure resembling a medieval king, particularly during twilight hours.

III. Architectural Marvel: Exploring the Design and Features of the Round Tower

A. A Fortified Form

1. The Power of the Circle:

Unlike many medieval keeps, which adopted a rectangular form, the Round Tower embraces a circular design. This seemingly simple choice offered significant advantages in warfare:

• Superior Defense Against Siege Engines: Battering rams, a common weapon used to breach castle walls, relied on concentrated force on a single point. The curved walls of the Round Tower deflected the impact, dispersing the force and making it more difficult to inflict significant damage.
• Eliminating Weak Points: Rectangular structures have corners, creating natural vulnerability points for attackers to exploit. A circular design eliminates these corners, offering a more continuous and robust defensive line.

2. A Tower of Strength:

Material and construction techniques further emphasized the tower’s defensive capabilities:

• Local Limestone: Constructed from Kentish ragstone, a local limestone renowned for its strength and durability, the Round Tower boasts walls that reach a staggering 15 feet thick at the base. This immense thickness created a formidable barrier that would have been incredibly difficult to breach.
• Crenellated Parapet: The top of the tower is crowned with a crenellated parapet featuring alternating merlons (raised sections) and crenels (gaps). This design provided a defensive platform for archers and soldiers to fire upon attackers attempting to scale the walls. Additionally, the gaps allowed defenders to drop projectiles like stones or boiling oil directly onto attackers below.
• Machicolations: The parapet incorporates machicolations, openings that project outwards from the wall. These openings allow defenders to drop projectiles and missiles directly down onto attackers attempting to climb the walls, offering an additional layer of defence.

3. A Fortified Complex: The Round Tower Within the Castle Walls

The Round Tower wasn’t solely a standalone structure. It served as the central keep, forming the heart of a comprehensive defensive system:

• Curtain Walls and Gateways: A series of curtain walls fortified with additional towers and gateways extended outwards from the base of the Round Tower. These walls enclosed an inner courtyard or ward, creating a layered defence.
• Concentric Defense: This layout created a concentric defence system. Attackers would have to breach multiple layers of fortification, including the curtain walls, outer towers, and finally, the formidable Round Tower itself. This system offered significant time for the castle defenders to mount a counter-attack.

B. Unveiling the Inner Workings

While the exterior boasts a stark and imposing presence, the Round Tower’s interior reveals a more practical and surprisingly well-equipped space.

1. Accessing the Upper Floors:

A central shaft within the tower’s thick walls provides access to the various floors. This central shaft likely housed a spiral staircase, although modern renovations have included a new staircase for improved visitor accessibility.

2. A Layered Living Space:

The Round Tower is divided into several floors, each serving a specific purpose. While the exact layout may have changed slightly over time, historical records suggest the following:

• Lower Floors: The lower floors likely served as storage spaces for provisions, weaponry, and other essential supplies. These floors may also house kitchens and other useful spaces.
• Upper Floors: The upper floors offered more comfortable living quarters. Larger chambers were likely used for sleeping and entertaining, while smaller rooms may have served as private offices or studies.
• Top Floor:  The top floor, directly beneath the crenellated parapet, may have been used as a lookout point and offered breathtaking panoramic views of the surrounding landscape.

3. Adapting to Royal Needs:

As the Round Tower transitioned from a purely military structure to a royal residence, modifications were made to enhance its livability. Windows were enlarged to allow for more natural light, and some chambers were likely decorated with fireplaces and ornate plasterwork to create a more comfortable environment.

C. Symbols of Power and Status

While the Round Tower retains its essential defensive character, subtle touches hint at its past role as a royal residence:

1. Royal Insignia:

While extensive heraldic displays may have adorned the exterior in earlier times, today, some remnants of royal insignia, such as coats of arms or monograms, might be found carved into stonework or embedded in decorative details.

2. Presence of Grand Halls or Ornately Decorated Chambers:

Historical accounts, particularly those surrounding Edward III’s renovations, suggest the presence of grander spaces within the Round Tower. These chambers may have been adorned with:

• Fireplaces: Large fireplaces would have provided warmth and a focal point for gatherings in the colder months.
• Ornate Plasterwork: Decorative plasterwork on ceilings or walls could have featured intricate designs, geometric patterns, or even heraldic motifs.
• Tapestries and Rich Furnishings: Luxury tapestries depicting historical scenes, heraldic emblems, or hunting scenes may have adorned the walls, while richly upholstered furniture would have added comfort and opulence.

3. Architectural Features Reflecting Changing Styles:

As mentioned earlier, the Round Tower witnessed numerous transformations throughout history. These changes are subtly reflected in the architectural details:

• Medieval Simplicity:  The core structure, with its thick walls, narrow windows, and emphasis on functionality, retains a distinctly medieval character.
• Gothic Touches:  Edward III’s renovations in the 14th Century likely incorporated some Gothic elements, such as the enlargement of windows and the potential use of pointed arches in doorways or fireplaces.
• Later Modifications:  While less prominent, later alterations may have included elements reflecting Tudor or Georgian architectural styles. These could be subtle details like changes in window frames, doorways, or even decorative plasterwork motifs.

The Round Tower’s architectural narrative presents a variety of styles. Instead, it showcases a fascinating layering of features, each reflecting the changing needs and tastes of the times.

IV. The Round Tower and the Monarchy

The Round Tower’s transformation from a military stronghold to a royal residence wasn’t overnight. Early modifications under Edward III in the 14th Century focused on creating more comfortable living quarters. Windows were enlarged for better light, and some chambers may have been adorned with fireplaces and decorative plasterwork.

Monarchs like Edward III and John of Gaunt likely spent time within the tower, enjoying the panoramic views and spacious chambers. While the Round Tower never became a primary residence, it served as a prestigious and secure space for monarchs, particularly for hosting visiting dignitaries. Even Henry VIII, known for his grand palaces, likely utilized the tower.

Throughout its existence, the Round Tower has borne silent witness to pivotal moments in British history. During the war, the tower’s formidable defences would have played a crucial role in safeguarding the monarchy. While not directly involved in major battles, the tower likely served as a secure storage space for valuables during conflicts like the English Civil War.
