Croolea is the first site of ruined houses along the western slope of Green Hill above Tofts at Quandale. In early rentals it is variously known as Cruly or Crowly. The nearby enclosure of Claypots [below left] was also known as Clay Pows.
According to the 1841 census, carried out on June 7th that year, Croolea was occupied by 55-year-old farmer John Clouston, for which he paid rent of £3 7s 0d. His wife was 45-year-old Christina and they had a fifteen-year-old daughter Betsy. When Quandale was cleared John Clouston went on to build a house on land at Claybank, Wasbister.
Cairn [below] is the next ruin, between Croolea and Breck.
Unfortunately I have no information regarding this site.
