Quothquan (also formerly spelled Couth-Boan, meaning "the beautiful hill"; Gaelic; Scottish Gaelic: '''A’ Choitcheann''', pronounced in Gaelic; Scottish Gaelic pronounced as /ə ˈxɔʰtʲçən̪ˠ/, meaning "the common"[1]) is a village in Libberton parish, South Lanarkshire, Scotland.[2] It is northwest of Biggar, and southeast of Lanark.
To the southwest is the 1098feet high hill Quothquan Law, topped by the remains of a hill fort. The hill comprises two elements, one is an enclosure to the southeast which is around 400feetby230feetft (byft). The other is a lower larger annexe to the northwest, with double ramparts and a medial ditch which has mostly been filled in.[3]
Quothquan has a village hall near the remains of the graveyard and the ruins of a small church. The original church was recorded in use as a schoolroom after 1724. A new church in the village was paid for in 1903 by Glasgow shipowner Sir Nathaniel Dunlop, who lived nearby.[4]
