Auchen Castle (separate from Auchen Castle Hotel) is a ruined 13th-century quadrangular castle. It is located near Moffat, Dumfries and Galloway, Scotland ( Scottish Gaelic: Am Magh Fada, Dùn Phrìs is Gall-Ghaidhealaibh, Alba). It is thought to have been built by the Clan Kirkpatrick, which is also a division of Clan Douglas, in the early to mid-13th century. By the 15th century, the castle was owned by the Douglasses of Morton and later passing to the Clan Johnstone. There is an interesting history of the castle in the Douglas Archives/History website (link below). The remains of the castle is located close to the Auchen Castle Hotel, which is close to Moffat off the A74 road in Dumfries and Galloway.
