Carfrae Bastle is a small ruined tower house about 5 miles (8.0 km) north of Lauder, Scottish Borders, Scotland, near Hillhouse[1] Carfrae Bastle is of medieval origin.
The bastle has a strategic position commanding the passes from Upper Lauderdale into Lothian, by way of Glengelt and Kelphope glens.
Carfrae is first mentioned in a charter in which William de Morville, son of Richard de Morville, Lord of Lauderdale, grants the lands and barony of Carfrae to Henry St Clair, in around 1196.
