Monument record MHG2362 - Mound, Sysa (Doom or Judgement)

Sysa (NR) OS 6" map, Caithness, 2nd ed., (1907)

This is a grass-covered mound, 200ft long, 165ft wide and with a max height of 30ft, which is said by RCAHMS (1911) to be natural, but which has a local reputation of being artificial and to be associated with the supernatural, especially with one occurrence on the day of the Battle of Clontarf in 1014.
The original OS surveyor (ONB 1872) describes it as similar to the Bass of Inverurie (NJ72SE 13) and suggests that the name derives from 'sise' meaning 'doom' or 'judgement'. The appearance of the mound is said to have been altered by cultivation, and a spring is said to have existed in a hollow on S face. The existence of spring would tend to confirm that the mound is natural.
