The Temple was allegedly built by Brutus. Diana (the Hunter) appeared to him in Malta about 1000BC, speaking of the “Great White Island”. Landing in Totnes, Devon, he came to London and built a temple to Diana/Herne. This lasted until about 700CE, when the first St Pauls was built.

A Roman altar stone dedicated to Diana was found in Foster Lane to the north of St. Paul's. It used to be kept in Goldsmith's House. The Location of Diana's chambers is shown on old OS maps on the south side of St. Paul's. St Paul's and many other sites form part of the geometry of the London Earthstars temple described in the book, Earthstars The Visionary Landscape (2000)
