This interactive map explores evolving interpretations of Avebury Henge (Wiltshire, England) through historic plans by antiquarians and archaeologists from the 17th–20th centuries. Plans are digitised from Ucko et al.'s (1991) book Avebury Reconsidered: From the 1660s to the 1990s . Use this map to:

• Compare plans by John Aubrey (1626–97), William Stukeley (1687–1765), Alexander Keiller (1889–1955), and Isobel Smith (1912–2005);
• Customise views with adjustable colours and opacity for each layer; and
• Take measurements, annotate features, and export maps as PNGs
