Clarence Quay is in the southwestern corner of the Tidal Harbour and Clarence Place used to run roughly parallel to it before the Pier District was demolished.
Clarence Place was the original terminus of the tram line but the railway level crossing gates caused delays and in 1898 the service was cut back to commence at the Crosswall. This photo is copied from "Dover's Tramways" by Robert J. Harley (Middleton Press ISBN 1 873793 24 3) without permission so Paul/Howard may wish to delete it. It shows Car 10 halted amongst the porters with their boxes of fish. The Royal Hotel is in the background and the Dover Castle Hotel joined on to it. See:

Clarence Quay can be seen at the top of this photo with two cargoships alongside and the Lord Warden Hotel in the background, joined to the Town Station by a passenger walkway.
Two of the cargoships of the Southern Railway can be seen alongside Clarence Quay with the Continental Goods Shed in the background. Clarence Quay and the adjoining South Pier were leased to the Southern Railway.
Clarence Quay today is the site of the Tug Haven. The two harbour tugs DHB Dauntless and DHB Doughty are seen here with the DHB dredger David Church, together with the lifeboat and range safety boats in the foreground. Cruise Terminal 1 (the old Marine Station) and Lord Warden House form the background. As can be seen, the whole of the area has been concreted over to provide hardstanding for trucks, a far cry from the bustling scene in the earlier tram photo. In the unlikely event that Terminal 2 ever sees the light of day, this entire area of docks will be filled in and become another barren waste of tarmac parking serving the new ferry berths.
