Ballagan, an estate, with a mansion and with a fine waterfall, in Strathblane parish, Stirlingshire. The mansion stands on the upper reach of the Blane river, called the Laggan Burn, ¾ mile E by N of Strathblane village, and commands, from its windows, a view of the waterfall, which, known as the Spout of Ballagan, makes a descent of 70 feet, and somewhat resembles Corra Linn.
