Muckrach Castle is a late 16th century stone L-plan tower house, founded by Patrick Grant. Of three storeys and a garret, with a projecting circular stair-wing crowned by a two storey watch-chamber, the tower is the original seat of the Grants of Rothiemurchus. The square main block has a first floor hall above a vaulted basement and in the re-entrant angle are a corbelled out stair-turret and the entrance. The tower is pierced with gun-loops and there was a large courtyard with ranges of buildings and round angle towers. After being ruinous and roofless, the castle was restored from 1978 but the courtyard is only foundations and grass covered mounds. A date stone of 1598, with the arms and initials of Patrick and his wife, plus the motto 'In God Is Al My Trest' is now over the entrance. 4 miles south-east is Castle Roy and 26 miles north is Brodie Castle.
