This limestone promontory projects 2km into the Bristol Channel south of Weston-Super-Mare. It is a fine example of a preserved ancient landscape which has survived because of the low intensity of subsequent landuse. On the south side of the Down is an accumulation of sediment, the sandcliff. The Down and sandcliff are in National Trust ownership and the area is a Site of Special Scientific Interest because of the Earth Science importance of the sandcliff and the presence of rare plant and animal species, particularly the white rock rose (Helianthemum appenninum).
At the east end of the Down is an Iron Age promontory hillfort. On the middle hump of the Down is an excavated Romano-Celtic temple of the fourth century AD. After the temple a small structure was built on its site and with it was a human burial. Around the temple and in the hump of the down to its west are the remains of ancient fields and a number of Bronze Age burial mounds. At the west end of the down is a well preserved nineteenth century and later fort. The remains of twentieth century gun emplacements lie at both ends of the Down.
This is one of the best sites in the estuary for the visitor. It is a beautiful landscape with visible archaeological sites and wonderful views of the estuary. The climb to the top of the Down by the steps is steep but there is a more gently foot route along a road to the east. Park at Brean Down caf� (leaflet available and small interpretation display). The round walk is a good 3 hours.
