That is an interesting montage of the old Merchant's Quay. I remember it as a kid....the surface car park for Roches Stores was just behind those buildings and there was an elaborate entry and exit (using the two lanes in the picture).
The St. Vincent's Hostel was in use towards the end, but the quay lost any sparkle as it was bought up in advance of the construction of the ugly monolithic Merchants Quay shopping center. At the very least, the old quay had character.
Here we have another picture by Nathaniel grogan painted c. 1800 and entitled Whipping the herring out of town. The events are situated against the background of the North gate into the City -alas no longer. The custom commemorated here refers to the tradition of the meat butchers ceremonously to dump herring out of the city at the end of Lent are welcome the arrival of Easter (and the eating of meat) by hoisting the leg of mutton!
George Atkinson's picture (about 1836/37) of emigrants on Anderson's Quay with the newly built St. Patrick's Church in Glanmire Road on the left. It was consecrated on 19 October 1836 by the smae group of prelates who had consecrated St. MAry's in Buttevant a week earlier.
