Monument Type: City Walls
Castle Gate is the smallest and one of the least elaborate of the city’s gates. It was opened through the walls in 1802, and is mainly constructed from uncoursed rubble shale and has a single segmental-arched opening over which the walkway is humped. It is used only for pedestrian access. An Irish Fortified House of the O’Dohertys of Inishowen was once located near this site inside the present City Walls.
