Walled Enclosure, Old Bea Farmhouse, Birsay

The Old Bea farmhouse buildings are located in Birsay on the northern coast road of the North Orkney Mainland. They are constructed from traditional flagstone and are arranged in a rectangular plan. The group includes the remains of a single-storey Orkney firehouse dating to around 1664, which was extended in the 19th century with a two-storey section added to the west gable. There are two doorways on the south elevation. The two-storey addition has been left without a roof since 2018, having previously featured a flagstone roof. The mid-17th century firehouse was raised by one storey during the late 20th century using reconstituted stone blocks.

At the rear (north) of the house is a long narrow former byre. To the south, there is a rectangular enclosure with a low flagstone wall. West of the enclosure are two adjoining single-storey gabled outbuildings, which have roofs covered with corrugated or 'crinkly tin' sheeting.
