Described by Richard Feachem (1977) as simply “a fort or fortified dwelling place,” they should not to be confused with hillforts. This is a certain species of large circular stone-walled monuments, sometimes ascribed as ‘Homesteads’ and thought by some to be collapsed brochs. Their precise nature cannot be ascertained until detailed antiquarian digs have been undertaken. These types of ‘fort’ are found in particular concentrations in central Scotland, especially Perthshire.
