During the Bronze Age (2,500 – 800 BC) the climate slowly became cooler although the sea level continued to rise and around 750 BC the sea started to breach the spits across the estuaries further south. This resulted in Walcott becoming part of a large peninsula with numerous islands and waterways in the south and east. This peninsula would have made an ideal area for man to colonise with fresh water, fishing and reeds (for thatch) in the west, sea fishing in the east. The good farming land and its isolation would have offered some degree of defence.
