Sea Wall,

Bridgwater Bay and a gap in the Sea Wall allows access to the beach at Burnham on Sea. This wall was built in1988 as replacement to the previous storm damaged structure,
The bay has the second-highest tidal range in the world, up to 36 feet (ca. 11 metres) and at very low tide the sea can recede 1.5 miles (2.41 km) ,

The curved waterway left of image is the mouth of the River Parrett.

The lower lighthouse, in the distance, was built in 1832 and is a grade 2 listed structure,
