The town of Chester sits close to the border with Wales in Cheshire, England. The town was founded by the Romans in 79 AD as a Roman fort. Chester is one of the best preserved walled cities in the British Isles. Pictured is the Eastgate Clock, which sits above the gate in the east wall of the city. Once the original entrance to the Roman fortress, the east gate was replaced by this arched entrance in 1768. In 1899, the clock was added above the east gate entrance to commemorate the diamond jubilee of Queen Victoria two years earlier. The clock is said to be the most photographed clock in England behind Big Ben.
