General Information

The Mulberry Harbours were two artificial port facilities designed to supply and support the allied forces in the period following the Normandy landings.

The harbour breakwaters were formed from a series of 200ft-long floating concrete caissons which were towed across the Channel and then sunk into position.

Of the 80 largest caissons 10 were constructed by the company. Eight were built in East India Dock Wet Basin with two part-built downstream before being towed upstream for completion.

Before the Wet Basin could be used it had to be dammed across the dock entrance and dewatered. More than 81,000 tonnes of rubble from bomb-damaged buildings was used to form a bed on which to build the caissons.
