This is the only part that remains of the castle first erected in Winchester by the Normans. Dating from the 1200s, it is one of the finest examples of a medieval hall in England, with its timber roof supported on columns of Purbeck marble. The first fortress here was erected by William the Conqueror after he'd subdued England. Henry III rebuilt a castle on its foundation. Once it was a royal seat, and the English Parliament met here for the first time in 1246. The castle played a part in English history, including the trial of Sir Walter Raleigh, who was condemned to death here in 1603 for conspiring against King James I.
