tomb is near the Stones of Stenness and the Ring of Brodgar on the
Orkney Mainland. This superb structure dates to somewhere around 3000BC.
The mound is 7.3 meters high and 35 meters in diameter. A ditch and low
bank surrounds it. The long, low entrance passage leads to the main
chamber which is about 4.5 meters square and would have been about 4.5
meters in height; however the roof collapsed after being entered by
Norsemen in the 12th century. These raiders left runic graffiti over
much of the main chamber stones. There are three subsidiary chambers in
the walls of the main chamber. At mid winter, the setting sun shines
down the passage and shines on the back wall of the tomb.
