Brean Down

Brean Down is a limestone promontory jutting into the Bristol Channel on the Somerset coast. It rises 97 metres above the water and stretches two and a half kilometres from the mainland near Burnham-on-Sea. Made of Carboniferous Limestone, it continues the line of the Mendip Hills and is joined underwater to Steep Holm and Flat Holm. The cliffs on its northern and southern sides contain fossils from marine deposits laid down 320 to 350 million years ago. Human activity began in the late Bronze Age and the site includes the remains of a Romano-Celtic temple and a 19th-century fort. The promontory is recognised as a Site of Special Scientific Interest for its geology and rare plants such as the white rock-rose. It has also been scheduled as an ancient monument because of its long history of occupation. Brean Down Fort, built in the 1860s and rearmed in the Second World War, stands at the seaward tip. In 1897 Guglielmo Marconi set a new wireless transmission record from the headland. The National Trust now owns the site, which supports a range of wildlife including peregrine falcons and nationally scarce plants. Visitors walk along the grassy ridge to the fort at the tip, where the views stretch across the channel to Wales. The southern slopes are bright with white rock-rose and wild thyme in summer, while the northern side is clothed in bracken and heather. Fossils can be found in the cliff ledges, and stonechats and linnets are common overhead. The fort’s gun emplacements and observation posts remain, offering a reminder of the headland’s military past.
