How To Get There Follow the A965 north out of Stromness. After about a couple of miles you will cross over a bridge, with the Loch of Stenness to your left. Just after the bridge there is a left turn up a small and bumpy track to the tomb. The site is signed. The substantial grassy mound of the chambered tomb of Unstan rises up from a promontory by the Loch of Stenness.
Entrance is gained via a low and narrow passage on the east side of the mound.
Large upright stones divide the chamber into compartments and there are compartments at each end of the cairn too. These end compartments seem once to have had massive stone shelves dividing them in two. There is also a small side chamber here, built into the western wall of the tomb. Look closely at the lintel stone of this chamber and you'll see some Norse runes and a carving of a bird. Not as impressive as the examples to be found just down the road at Maes Howe , but interesting all the same.
