Dunninald has a history of at least a thousand years. The name is derived from the gaelic, dun a castle and ard, a high place. A second house was built about 1590, to replace the old tower. This was some four hundred yards inland and was at the foot of the present-day beech avenue, next to the walled garden.
By 1811 the second house was some 230 years old and the new owner, Peter Arkley, commissioned James Gillespie Graham to built a new house. This was designed by the architect James Gillespie Graham in the gothic revival style, building started in 1819 and the house was completed in 1824.
Guided tours of the castle explain the history of the house, the collections of furniture, paintings and displays of fine needlework photographs and memorabilia, examples of fine plasterwork and trompe l'oeil can also be seen. Tours take approximately 40 minutes and start on the hour and half hour.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
