Hoy, Lyness, Wee Fea, Former Naval Headquarters And Communications Centre

The former Naval Headquarters and Communications Centre, built by the Royal Marine Engineers in 1943, is a large concrete structure with a rectangular plan, serving as a communications and signal station during the Second World War. It is situated on Wee Fea, overlooking Lyness, and is built into a bank with a ditch separating it from the hill to the northwest and southwest.

On the northwest elevation, there is an opening to the left that once had a timber forestair, which is now missing, and a porthole opening to the right flank, along with two additional openings further right. A set-back opening is located at the far left, with concrete stairs leading up to a door. The southwest elevation features a small square window with external pipes visible below. The southeast elevation is marked by several porthole openings and a window at the far left, along with an advanced three-sided section to the right that has windows on each face. There is also a window opening at the far right, and numerous ventilation slits are distributed along this elevation.

The northeast elevation includes three window openings and a concrete forestair at the far right that leads to an opening in the right return. The flat roof is notable for containing remnants of signal mountings, a brick water tank, and other concrete structures.
