Bishops Gate, Derry City Walls (3D Model)
Bishop’s Gate was one of the four original entrances to the city. The current gate was erected in 1789 in commemoration of the 1689 siege. In 1789 the present gate was erected in a triumphal arch style to celebrate the centenary of the ‘Shutting of the Gates’. The gate is constructed from buff ashlar sandstone and has a central semi-circular-arched vehicular opening flanked by two flat-arched pedestrian passages.
The gate architect was H.A. Baker, with the sculpted heahd keystones representing the River Foyle (external) and the River Boyne(internal) designed by Edward Smyth, who had sculptured the thirteen riverine heads on the Dublin Custom House in c.1784. On either side of the gate are steps giving access to the City Walls.
