A working estate.
Old Place of Mochrum is sometimes known as Castle of Mochrum or Drumwalt. The Old Place of Mochrum was formerly the seat of the Dunbars. The West tower was built by Sir John Dunbar some time between 1474 - 150, and according to the INVENTORY it probably dates from circa 1500. According to both the INVENTORY and MacGibbon and Ross, the south tower resembles in plan Carsluith, built in 1581. The property was acquired by John Patrick Crichton-Stuart, the Third Marquess of Bute, who began restoration work on the Old Place of Mochrum; work was completed under John Crichton-Stuart, the Fourth Marquess of Bute. The castle was restored from a roofless ruin. Restoration work began in 1873 to designs by Richard Park. The west tower was restored from 1873 - 1874. The south or Ladies' Tower was restored and the hall connecting the two towers was built between 1877 - 1898. The two ranges of buildings to the north and east were built from 1900 - 1902; the north range was built upon the foundations of an earlier wing, probably of late 15th to early 16th century date. Restoration work was continued by Robert Weir Schultz from 1903 - 1908; in a letter, dated 26 May 1903, Schultz states that it has been "settled with park about the transfer of the work". The connecting hall was remodelled to incorporate a chapel, probably by Schultz in or after 1912, with Park's
crowstepped gables and dormerheads being replaced by a straight parapet. Schultz's work on the interior consisted of installing panelling and chimneypieces, and designing and commissioning furniture.
During restoration, the crowsteps were reproduced in the style which is peculiar to Galloway. See separate listings for Old Place of Mochrum: Bridge; Cartshed; Electricity House and Sawmill.
