Fir Clump Stone Circle was a stone circle in Burderop Wood near Wroughton, Wiltshire, in South West England. The ring was part of a tradition of stone circle construction that spread throughout much of Britain, Ireland, and Brittany during the Late Neolithic and Early Bronze Age, over a period between 3300 and 900 BCE. The purpose of such monuments is unknown, although some archaeologists speculate that the stones represented supernatural entities for the circle's builders.
A double concentric circle consisting of sarsen megaliths, the Fir Clump stone circle was oval-shaped. The outer ring measured 107 metres (351 ft) by 86.5 metres (284 ft) in diameter, and the inner ring 86.5 metres (284 ft) by 73.7 metres (242 ft). It was one of at least seven stone circles that are known to have been erected in the area south of Swindon in northern Wiltshire. Around the 1860s, the megaliths of Fir Clump stone circle were levelled. In the 1890s, the antiquarian A. D. Passmore observed that the circle was no longer visible. Some of the fallen megaliths were rediscovered in 1965 by the archaeologist Richard Reiss, who described and measured the monument. In 1969, these stones were removed during construction of the M4 motorway.
