In Early British Trackways Alfred Watkins theorised that a ley line passed along the Malvern Hills through several wells including St Ann's Well, Holy Well, Walms Well and St. Pewtress Well. Interest in Watkin's theories subsided in the 1930s but saw a revival in the late 1960s. In The Ley Hunter's Companion (1979) Paul Devereux theorised that a 10-mile alignment he called the Malvern Ley passed through St Ann's Well, the Wyche Cutting, a section of the Shire Ditch, Midsummer Hill, Whiteleaved Oak, Redmarley D'Abitot and Pauntley. In City of Revelation (1973) British author John Michell theorised that Whiteleaved Oak is the centre of a circular alignment he called the Circle of Perpetual Choirs and is equidistant from Glastonbury, Stonehenge, Goring-on-Thames and Llantwit Major. The theory was investigated by the British Society of Dowsers and used as background material by Phil Rickman in his novel The Remains of an Altar (2006).
