Boundary Walls, Head Keeper's Cottage, Former Kinnaird Head Lighthouse, Stevenson Road, Fraserburgh

The former Kinnaird Head Lighthouse comprises a complex of buildings including a four-storey tower house with an integrated lighthouse, three former keepers' cottages, an engine house, and a fog horn, all situated on a clifftop north of Fraserburgh. As of 2016, the site functions as a museum.

The tower house was likely built by Sir Alexander Fraser of Philorth around 1570. It incorporates a circular lighthouse on its northeast side, with a domed lantern projecting through the roof. The lighthouse itself was initially constructed in 1787 by Thomas Smith and remodelled in 1824 by Robert Stevenson. The tower house is built of harled rubble with a corbelled parapet and round bartizans at the corners, alongside square bartizans at the centres of the elevations. The lighthouse section is a tower of granite ashlar, featuring a projecting lantern. This lantern has two encircling walkways above a ground floor, each with metal railings; the lower walkway is corbelled. The lantern’s glass is diamond-paned. Window openings are irregularly spaced, featuring a large window within the stair tower. The majority of the windows are timber sash and case with a 6-over-6 glazing pattern, although some are smaller.

The lighthouse tower's interior, viewed in 2016, includes an internal stone spiral staircase with metal balusters and a timber handrail. The lantern chamber contains a large circular brass frame supporting the lens. The basement is vaulted. Other rooms within the tower were converted into keepers' accommodation in the 1830s, and contain 6-panel timber doors.

The former keepers' cottages and engine house are located to the north, southeast, and south of the lighthouse. A pair of cottages to the southeast date from 1824, while others were constructed in 1902. These are single-storey, symmetrical, flat-roofed buildings built of white harled rubble with contrasting mustard margins, incorporating a base course, blocking courses and quoins. The 1824 cottages feature central, hexagonal chimney stacks.

A coped rubble boundary wall is situated to the east, west and south of the southern keepers’ cottage. The windows of the cottages are mostly timber sash and case with a 4-pane glazing pattern. Interiors of the cottages retain small rooms with some 4-panel timber doors and carved fire surrounds.

A fog horn, constructed in 1902, is located to the north of the site, on the cliff edge, facing out to sea. It consists of a concrete, semi-circular structure with a metal horn on its roof.
