In 1993, the Lavant drum, a small Neolithic cylinder, was discovered during excavations at Chalk Pit Lane. It is one of only four objects of its type. The other three, the Folkton drums, were discovered in 1889 in North Yorkshire. It has been suggested that these objects were tools used to measure cord to standard lengths which were used in the construction of monuments such as Stonehenge and the timber circle at Durrington Walls.
