The Brean Down temple during excavation, showing the plinths of the porch, vestibule and cella. (ApSimon 1965: Plate 11a)

Brean Down (ST 293587), a promontory on the southern side of the Bristol Channel, projects dramatically for a mile into the sea between Burnham-on-Sea and Weston-super-Mare, south-west of Bristol. A metal detectorist found the single curse tablet known from the site. Detailed knowledge of the context from which it derives is lacking but it is reasonable to assume that it was associated with the Roman temple on the promontory, sited on downland now owned by the National Trust. There is no visible indicator of the temple's existence, but visible monuments surviving on the Down include a Bronze Age barrow and Iron Age or Roman field systems. A Bronze Age settlement lies at its eastern foot.

The temple and its surroundings were excavated in the 1950s. From those excavations a considerable amount of information was derived concerning both the layout and architecture of the shrine and its ancillary buildings.
