The current Stolzembourg castle was built on the ruins of the medieval castle in 1898 in the style of a Scottish country house.
In the 12th century, a tower was built to keep watch over the road along the River Our. The first mention of a fortress was in 1315. In 1454, the governor Antoine de Croÿ pulled down the castle. After it had been rebuilt, it was finally destroyed by the French troops of Louis XIV in 1679. In 1898, a Scottish-style country house was built on the ruins.
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.
