There are several archaeological sites on Sanday, the most impressive being this chambered tomb, similar to Maeshowe and dating from the 3rd millennium BC. It has triple walls, a main chamber and six smaller cells.
This museum in the former temperance hall has intriguing displays on various aspects of island history, including fishing, WWI, archaeology and shipwrecks. In an adjacent field a typical croft house is preserved.
Right at Sanday's northeastern tip, this is a major prehistoric funerary complex with over 500 graves from the Bronze Age as well as burial cairns and midden deposits.
