First recorded as the Mormaerdom of Menteith, it became the Earldom of Menteith. Gille Críst is the first known mormaer. The lands and the earldom passed to Walter Comyn (d. 1258) in right of his wife Isabella, and then through Isabella's sister Mary to Stewarts, and finally to the Grahams, becoming extinct in 1694.
The Lake of Menteith, situated 24 miles south of Loch Venachar, measures 14 miles long by 1 mile broad, and contains three islands. On Inchmahome (Innis MoCholmaig, island of St Colmaig) stand the ruins of Inchmahome Priory, an Augustinian priory founded in 1238 by Walter Comyn, and built in the Early English style, with an ornate western doorway. Queen Mary I of Scotland, when a child of four, lived on the island for a few weeks before her departure to Dumbarton Castle, and on to France in 1548. On Inch Talla stands the ruined tower of the earls of Menteith, dating from 1428.
The village of Port of Monteith stands on the north shore of the lake.
