Description

FERRYQUAYGATE INTRO

NISMR No.: LDY014:033

Monument Type: City Walls

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 1866. 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 thirteen apprentices to prevent Jacobite troops entering the city, leading to the siege of 1689. The later carved heads represent the Revs George Walker and James Gordon. The present structure was built of brown ashlar sandstone. It has a central semi-circular-arched vehicular opening flanked by two semi-circular-arched pedestrian passages
