LDY014:033 Ferryquay Gate is located on the site of one of the four original gates. The gate originally had a drawbridge and Tower; this was replaced by the present day gate in 1865. It probably led down to the ferry and later, to the first city bridge. It was this gate that on December 7th 1688 was closed by the 13 apprentices to prevent Jacobite troops entering the city, leading to the siege of 1689. The present gate was built in 1866, and the carved heads represent the Revs George Walker and James Gordon. The present structure was built in 1866 of brown ashlar sandstone. It has a central semi-circular-arched vehicular opening flanked by two semi-circular-arched pedestrian passages Derry~Londonderry: A guide to the historic city walls, Northern Ireland Environment Agency
