The East Gate was considered the main entrance to the Roman Fortress of Chester and was therefore the most elaborate. It bears similarities to the Kings Gate at Caernarvon Castle, suggesting that it was built in the early 14th century. From the late 18th century bridges to expand the Walls promenade replaced the four main medieval gates. The City Arms are carved on the keystone facing Foregate Street and the Grosvenor Arms on the keystone facing Eastgate Street. The clock was added to commemorate Queen Victoria’s Diamond Jubilee.
