Eastgate and Eastgate Clock in Chester, Cheshire, England, stand on the site of the original entrance to the Roman fortress of Deva Victrix. It is a prominent landmark in the city of Chester and is said to be the most photographed clock in England after Big Ben.
The original gate was guarded by a timber tower which was replaced by a stone tower in the 2nd century, and this in turn was replaced probably in the 14th century. The present gateway dates from 1768 and is a three-arched sandstone structure which carries the walkway forming part of Chester city walls. In 1899 a clock was added to the top of the gateway to celebrate the diamond jubilee of Queen Victoria two years earlier. It is carried on openwork iron pylons, has a clock face on all four sides, and a copper ogee cupola. The clock was designed by the Chester architect John Douglas. The whole structure, gateway and clock, was designated as a Grade I listed building on 28 July 1955.
Chester was first established as a Roman fortress and town, known as Deva Victrix in about AD 74 or 75. The fortress was in the shape of a rectangle with rounded corners. This was protected by a turf and earth rampart on which was a timber palisade, and outside this was a V-shaped ditch. On each of the sides was a gate; the gate on the east side has survived as the Eastgate. It was defended by a timber tower. The road running through the gate led to Manchester, then across the Pennines to York. It is thought that outside the fortress, this road was lined by timber buildings which were used as shops or for other kinds of commercial activities. Just outside the gate, to the north, was a large open area used as a parade ground. From about AD 100 the defences of the fortress were reinforced by a sandstone wall and at this time the gates and their towers were rebuilt in stone.
