Aquahorthies College or the House of Aquahorthies (alternatively spelt Aquhorthies or Aquhorties);[1] was a Catholic seminary in Scotland from 1799 to 1829. At the time it was the only Catholic seminary in the east of Scotland. The house still stands today, located between Blairdaff and Inverurie in Aberdeenshire, as a private residence. It is a Category A listed building and is very close to the Easter Aquhorthies stone circle.[2]
