Baldenau Castle was built by the Trier Elector and Archbishop Balduin of Luxemburg around the year 1320. Initially designed as a hunting lodge, it was later on, beginning in 1324, completed to a residential seat through the construction of additional buildings, stables, and barns. The principal Balduin who initiated the building and gave it his name, was born in 1285 as the youngest son of Count Henry VI. of Luxemburg.
The most impressive part of castle is the keep, 25m height and 10m width. The surrounding moat is 12m wide. During the Thirty Years' War (1618-1648), Baldenau Castle was seriously damaged by Swedish troops, but reconstructed throughout the years 1649-1654. However, only 35 years later, in 1689, the French army devastated the castle.
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.
