At the Southwest tip of the Inchmurrin island are the ruins of the 14th century castle built by Duncan the Eighth Earl of Lennox. The castle is recorded as having been completed by 1393 and the Earls of Lennox took up residence in the 14th century when they moved from their castle in Balloch during the plague. The castle was composed of three rooms, outbuildings and a courtyard.
King Robert the I is believed to have been given refuge here by the Fifth Earl of Lennox after his defeat by the MacDougalls of Lorne. King Robert the I also established a deer park here in the 14th century.
Isabella, countess of Albany and the daughter of the Eighth earl of Lennox was exiled here after 1425 when her husband, father and two sons were all executed on the same day at Stirling by King James I. She lived at the castle for the rest of her life and died on the island in 1460 after which the castle was abandoned. It is recorded that Sir John Colquhoun of Luss was killed here in 1439 during a raid led by Lachlan MacLean.
King James the IV used the castle as a hunting lodge around 1506 as did King James the VI in later years.
The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
