The archaeological monuments at Allt Chrysall (Allt Easdale), Bentangaval, were discovered in 1990 during the archaeological survey which preceded the building of the Vatersay causeway and its approach road. Excavations have revealed at least six phases of human occupation of this 'preferred site' overlooking the sound of Vatersay, beginning about 4500 years ago.

The SEARCH (field archaeology) team will be at Allt Chrysal between June 15th and 3rd July '05. I believe that all are welcome to pop along and have a look at what they are doing
