On the Mainland side of the causeway is Birsay Village (also called Palace),
containing the ruins of the Earl's Palace built in the late 16th century
by the infamous Earl Robert Stewart. The nearby church of St Magnus is said
to be the place where St Magnus' body was taken after being murdered by
a cook on his cousin Hakon's order.
The square tower on Marwick head is a memorial to the loss of the crew of HMS Hampshire, including Lord Kitchener of Khartoum, on 5th June 1916. The best (although steep) approach to this tower is from Marwick Bay although there is a car park at the bottom of the hill which offers an easier approach.
South of Marwick bay, at Sandside Geo are some beautifully restored fishermen's huts with flag 'nousts' (places where boats were kept on land). The huts blend into the shoreline and are not always seen until close by.
Kirbuster Farm Museum is a good example of an early 19th century farmhouse and steading and is well worth a visit.
