PORTLAND

SY67SE CASTLETOWN PIER, H.M. Naval Base
969-1/1/155 (North side)
Mulberry Harbour, two sections c
115m N of pier

II

Two 'Phoenix' units of former Mulberry Harbour complex. 1944.
Reinforced concrete. Two units of the 'floating harbour'
produced to assist in the Normandy invasion of 1944. Eight of
these units were located in the Harbour in 1946 to provide
protection for new pier construction; two of these now remain,
permanently moored, and lying due N/S, about 115m north of
Castletown Pier. Each unit is c 60m long, 20m wide, and 15m
high. Most of the Harbour was towed across to serve the D-day
landing of June 6th 1944 on the Normandy beaches; these two
sections are appropriately sited in Portland Harbour as a
reminder of this remarkable enterprise.
