Started in about 1200 as 4 towers, of which 2 survive, it was originally called Freuchie, changed by a charter from William and Mary to the Castle of Grant.

It was altered and added to by Robert Adam, who in the eighteenth century made the front the back!

Castle Grant has the oldest surviving Pine Roof Structure in Britain dating back to 1540. It is likely that the timber used was local, as Strathspey is virtually unique in Scotland in that timber was not imported into the area. One beam, known as the Lochindorb Beam, was reputed to be used to hang sheep stealers!
