Geography and geology
Graemsay is sometimes referred to locally, as 'Orkney's green isle' due to its lush green vegetation cover.
As with many other Orkney Islands, there is a connection to the Celtic Church, possibly a pre-Norse one. There are the remains of two early churches, dedicated to St Bride and to St Columba., who are both saints of Irish origin.
At the Point of Oxan in the far north west, in Burra Sound, are block ships, which were scuttled deliberately during World War II. This is a common feature of the straits and former straits around Scapa Flow
The primary school closed in 1996 and the island's children travel daily by boat to school in Stromness on the ferry 'Graemsay.'
Two lighthouses are present on Graemsay: Hoy Sound Low and Hoy Sound High located at the extremities of the northern side of the island. The lights were built in 1851 on project by Alan Stevenson; both are cylindrical tower with balcony and lantern, even if of different heights, white painted with black lantern and the typical ochre trims.
The Hoy High Light, known as Graemsay Island Range Rear, is 33 metres (108 ft) high and has a white and red occulting light every 8 seconds depending on the directions.
The Hoy Low Light (Graemsay Island Range Front) is 12 metres (39 ft) high and is distinguished by a white isophase light every 3 seconds. The two Range lighthouses direct the ships towards the Hoy Sound from the Atlantic.
