The Sanctuary 1925

 Photograph taken by William Williams during an overseas holiday he took with Lydia Williams between 1925 and 1927.

"Signpost on road, barrow mound in distance, [Avebury?], Wiltshire, England. Williams, Edgar Richard, 1891-1983: Photographs and papers. Ref: 1/4-100423-F. Alexander Turnbull Library, Wellington, New Zealand. /records/32048512"

The archive has a several interesting other local photographs of the Wansdyke and Avebury 

It is always satisfying when you recognise a view in an old photograph:

The photograph was taken before Maud Cunnington rediscovered and excavated The Sanctuary in 1930 just to the right of the hedge in the photo.

As to what the notice says, who knows?
