Sandby’s watercolour view depicts a coach and horse stopped on the public road that winds up Castle Hill around 1765, with the Devil’s Tower (now Edward III tower) straight ahead. This road existed until 1823 when George IV ordered the closure of the path from the southeastern corner of the castle to the river crossing at Datchet, sending it further to the south through Park Street.

By the time that the architect Sir Jeffry Wyatville had finished his alterations to the castle in the 1820s, this roadway culminated in St George’s Gateway. The Round Tower to the left was raised in height, and the buildings seen here on the right, previously purchased in 1779, had all been cleared. During the latter part of the twentieth century, the main use of this area was as a car park. The Jubilee Garden was created on this site as a more attractive entrance to the castle for visitors.
