White Barrow

White Barrow is a large Neolithic long barrow just below the crest of Copehill Down on Salisbury Plain, just south of the village of Tilshead in Wiltshire [1]. It is a scheduled monument, and the first ancient monument to be purchased by the National Trust [1]. White Barrow is 77.5 m long and approximately 47 m wide (including the surrounding ditch) [1]. It has never been fully excavated, but dating of materials found in and around it suggests that it dates from 3500 to 4000 BC, making it contemporary with other long barrows on Salisbury Plain [1]. A geophysical survey by English Heritage in 1997 found evidence of a possible burial chamber or mortuary cairn inside the barrow, and an arc of post pits at its eastern end [1].
