By contast, Kenilworth was, for most of its history, the Kings's own castle in the region, which provided a base from which the King could watch over his barons, both in Warwickshire and other parts of the midlands. This differentiation between provincial Warwick and the royalist Kenilworth, runs through their histories, and was the origin of the very different fates of the two castles.
Royalist forces then lay siege to Warwick Castle. Charles I, who was then at York, began to bring his forces to the siege of Warwick, and at the same time Parliamentary reinforcements were also brought to the area from the south. These forces first met in a skirmish near Southam, which was soon followed by the first major battle of the Civil War at Edgehill.
For much of the Civil War Warwick was a parliamentary garrison. At the end of the civil war it was returned to the care of Lord Brooke. By contrast, the magnificent Kenilworth Castle, which had had royalist sympathies, was partially demolished and is now a ruin.

There are two major castles in Warwickshire: Warwick and Kenilworth Castle, which is about 5 miles away. The development and evolution of both Warwick and Kenilworth was very similar. Both commenced as motte-and-bailey castles, with a mound, wooden buildings and enclosures, then stone fortress towers were built, then curtain walls became added, and then both developed into lavish palaces.

Warwick Castle During The Civil War
Before the outbreak of the English Civil War, Warwick Castle was a centre of Protestant and Puritan sympathy. The castle was a refuge for Puritan priests. At the time of the outbreak of the War, Warwick Castle was the home of Lord Brooke, a foremost Puritan intellectual. Coventry also had Puritan sympathies, and one of the first actions of the civil war was the transfer of the Coventry powder magazine and munitions to the security of Warwick Castle.
