Showery Tor is a rocky outcrop on a ridge-top approximately 0.6 kilometres (0.37 mi) north of the Rough Tor summit, near Camelford on Bodmin Moor in Cornwall. It is notable for its rock formations and prehistoric monuments. The Tor is a prominent landmark for a wide area. It consists of a natural 5-metre (16 ft) outcrop of weathered granite enveloped by a giant man-made ring cairn of stones, each up to 30 metres (98 ft) in diameter and 1.2 metres (3.9 ft) high. Christopher Tilley has estimated the height of the cairn on which the outcrop stands to be 3 metres (9.8 ft).
