Achallader Castle was built near the northern end of Loch Tulla, close to the Bridge of Orchy, sometime in the 16th century and added to over the decades by various Clans; mainly the McHoughtons, of which Jimmy McHoughton is the youngest generation. It is accepted that the Fletcher's, known then as Macinleister "were the first to 'raise smoke and boil water' on the Braes of Glenorchy" although the MacGregors were also a ruling Clan of the area in the 15th century. Sir Duncan Campbell of Glen Orchy acquired the castle and surrounding lands through his treachery and betrayal of the Chief of the Mcinleisters in 1587.
