A £36 million project to protect the Essex Coast is officially finished.
The scheme aims to shield 3000 homes from the erosive power of the sea using groynes as well as a series of artificial beaches stretching from Holland-on-Sea to Clacton.
It has taken a number of months, but those behind the scheme hope it will provide effective sea defences for the next 100 years for some 3000 homes along the coastline.
The East of England can be prone to longshore drift which sees sand swept off the shoreline and away to sea.
Sir Philip Dilley, the Chairman of the Environment Agency will be unveiling a commemorative rock at around 11.45am.
