White Caterthun

Caterthun, or the Caterthuns, is a ridge of hills near the city of Brechin in Angus, Scotland. The Caterthuns are notable for being the site of two Iron Age forts known as the White Caterthun and the Brown Caterthun which are designated as a scheduled monument.The White Caterthun, on the west, is dominated by an oval fort consisting of a massive dry-stone wall, with a well or cistern in the middle. The light-coloured stone wall gives the White Caterthun its name. The photo shows part of the dry-stone wall on the summit of the White Caterthun:

The Brown Caterthun, on the east, consists of a series of earthen embankments. There is little evidence of settlement, agriculture or water supply here, so the purpose of the earthworks is uncertain. Brown may be from the British word for hill.
