The Beauchamp Tower. This was built by Edward I in 1281 when it replaced a fortified gatehouse that stood on this site. Notable for using a large amount of brick as opposed to stone for its construction which at the time was an innovative approach. The tower was sued as a prison for high ranking prisoners. Said to be named after Thomas Beauchamp, Earl of Warwick, who was a prisoner here between 1397 and 1399.
Also known as Cobham's Tower after Henry Brooke, Lord Cobham, who died here after 14 years of imprisonment. Opened to visitors in the 1800's.
