This is one wall I would try to put back up before Halloween (from The Scotsman):

NEW evidence has been unearthed suggesting Orkney islanders once built a physical barrier between the land of the living and the spirit world.

Archaeologists are working on a Neolithic settlement, dating back nearly 5,000 years.

Only a small part of the Ness of Brodgar site has been unearthed, but already experts say it has given up fascinating discoveries and is helping them better understand the wider Neolithic complex between the Ring of Brodgar stone circle and the standing stones of Stenness.

It is even suggested that the remains of the unusual buildings recovered at Ness of Brodgar could be as historically significant as the islands' famous Skara Brae village.

Village of Skara Brae

"On the far curving shore of the bay lies Skara Brae, hazy through the sea-haar."
