Kenilworth Castle is a ruined castle located in the town of Kenilworth in Warwickshire, England. The castle was originally built as a Norman fortress in the 12th century and was later expanded and improved by various owners over the centuries, including King John, Henry III, and Queen Elizabeth I.

Kenilworth Castle, played an important role in British history for over 500 years. The site was fortified by the Saxons, and Kenilworth is mentioned in William the Conqueror’s Domesday Book of 1086. The castle is built almost entirely from local new red sandstone.
Kenilworth Castle History
The first castle at Kenilworth was erected in 1120 Geoffrey de Clinton. In 1173 the palace became a Royal Castle. In 1252 Henry III gave it away to Simon de Montfort, Earl of Leicester. The castle was handed to John of Gaunt, son of Edward III, and later became a royal palace. The castle was leased by John Dudley the Duke of Northumberland in 1553.
One of the most significant events in the castle’s history was the six-month siege it endured during the English Civil War in 1649. The castle was captured by Parliamentary forces and was subsequently slighted (damaged) to prevent it from being used again as a fortress.
A castle 500 years in the making
The castle went through several transformations over the centuries. The Norman earth and wood castle became a local sandstone castle with improved defences. This in turn was redesigned to focus on comfort and luxury rather than strength of defence, eventually becoming an Elizabethan style palace. In its final incarnation, the castle’s gatehouse was transformed into a dwelling, while the rest of the castle lay in ruins.

The 3-story rectangular keep dates back to the earliest stone construction in the 1100’s, but the changes made over the centuries (such as the larger Tudor windows) are easily visible. The kitchen was near the castle keep – kept separate to prevent fire – with other service buildings in the same location.
John of Gaunt’s Great Hall
The Great Hall built by John of Gaunt has lost its flooring, but it can be viewed from the undercroft or basement. The walls of the hall are still standing, along with evidence of an imposing vaulted ceiling, tall windows, window seats for work requiring more light, and a large fireplace.
Kenilworth Castle featured six towers at different times during its history.
Mortimer’s Tower
Mortimer’s Tower guarded the entrance to the outer bailey, and was essentially a gatehouse. The narrow passage through the tower, with thick walls and arrow slits above, meant that it could be defended by a small force of men.
Lunn’s Tower
Lunn’s Tower was part of the later defensive wall built by King John, and as such was designed for military purposes rather than comfort.
The Water Tower
The Water Tower, on the other hand, was much more comfortable, with ample fireplaces and large windows. It was added to the castle by Thomas, Earl of Lancaster and known as the Water tower because it overlooked the lower pool.
Mervyn’s Tower – The Strong Tower
Also known as the Strong Tower, it was known as such because of its unusually robust design, featuring stone vaulting across all floors. The Strong Tower, three floors high, contained domestic facilities such as the pantry and the buttery.
Saintlowe Tower and Gaunt’s Tower
Finally, Saintlowe Tower and Gaunt’s Tower were built by John of Gaunt to provide luxurious accommodations for himself and for important guests.
Leicester’s Great Tower
Other buildings at Kenilworth include the gatehouse and living quarters that were constructed by Sir Robert Dudley, Earl of Leicester, during the reign of Elizabeth I.
Dudley, a favourite of Elizabeth, built the living quarters specifically for her visits. Its three stories each contained a group of rooms, including a sitting room, a luxurious bedroom, and special decorative elements such as elaborate fireplaces.

Leicester’s building was four floors high and built in a fashionable contemporary Tudor style with “brittle, thin walls and grids of windows”. The building was intended to appear well-proportioned alongside the ancient great tower, one of the reasons for its considerable height.
Leicester’s building set the style for later Elizabethan country house design, especially in the Midlands, with Hardwick Hall being a classic example. Modern viewing platforms, installed in 2014, provide views from Elizabeth I’s’s former bedroom.

Like many once-magnificent castles of Norman and medieval England, Kenilworth was devastated by the Civil War that began in 1642.

The gatehouse was converted to a residence and the rest of the castle was left to decay. By the 19th century the castle was an abandoned ruin.
