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 back into a dwelling house from 1978 but its 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 at Balliemore is Castle Roy and 26 miles north at Dyke is Brodie Castle.
