MacLellan's Castle in the town of Kirkcudbright, in Galloway, was built in the late 16th century. It stands in the centre of Kirkcudbright, on the south side of the River Dee which flows into the Solway Firth. The L-plan castle was the residence of the MacLellan family from whom it derived its name. The family sold the castle in 1752, and from 1782 to 1912 it was held by the Earls of Selkirk. Today, the site is in the care of Historic Environment Scotland.
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.
