1842 Tithe map showing The Custom House of 1812, and the Dry Dock of 1814; The grounds of the Custom House led down to a short slip, for Custom Officers to be rowed out to ships. The Wharf and Slip were there in 1842. The Bonded Store did not exist as it was in the position now occupied by the old Trinity House Depot (in 1861 the whole area was taken over by Trinity House for the construction of Wolf Rock Lighthouse, and so that gives the date for the erection of the 'New' Bonded Store, as seen in the 1875 OS map). I have photographs of the lower area of the yards, taken before 1860 and 1915 looking up Quay Street (I will post up when I get a chance). Remember, the Dry Dock Gates are 195 years old.
