Sherborne Old Castle (English Heritage)

After withstanding two sieges during the Civil War, only the Southwest Gatehouse and parts of the castle, including the Great Tower and the North Range, now survive. Loved by Sir Walter Raleigh, he leased the castle but when he was imprisoned in the Tower of London for marrying one of Queen Elizabeth I's maids of honour without her permission, it was then leased out but remained a favourite home of the famous explorer.
