Holborn Head is a headland on the north-facing Atlantic coast of Caithness, in the Highland area of Scotland.
[1] The name Holborn appears Norse in origin, meaning hillfort, and the headland may be the Tarvedunum promotorium noted by Ptolemy.
[4] One source says no radiocarbon dating, or excavation for stratified remains has been done at the fort, so its age is unknown.
[5] Another says it is Early Bronze Age to Pictish, possibly 2400 BC to 900 AD,[6] and another says Count Moddan, one of the Earls of Orkney,[2] in the early 11th century, had his army on promontario Thorsnesia,[7] which its source takes to be Holburn Head.
After entering the upper floor front doorway there is a vestibule with 2 entrances, one to the Lightkeepers House and the other to the Lighthouse Tower.
