These photographs are from the 1920's and are common views overlooking the harbour. When scanned the background detail can give at lot of information like in the top photograph. The sluice or "tunnel" at the back of the harbour looks like an entrance to a cave. In the background the Metrople Hotel is in its former glory and Holy Trinity Church dominates the skyline. The other photgraph below of the Harbour was more than likely taken on the same day from the Parade.
I have added this photograph with excellent detail of the Parade, outside the White Hart hotel is a open top double decker bus destined for Westgate and Birchington.
These photographs are from my collection, please feel free to download and copy for your collection or whatever.
