St Fergus (Scottish Gaelic: Peit Fhearghais) is a village in Aberdeenshire, Scotland, formerly in the county of Banffshire. St Fergus lies a mile from the North Sea coast and three miles northwest of Peterhead. As you cross the "chain brigg" over the river Ugie at Balmoor House you enter the Parish of St Fergus. On the left in the trees are the remains of Inverugie Castle and further up river are the remains of Ravenscraig Castle.
