Alzey Castle, constructed in the 13th century, was the residence and headquarters of the district administration. The castle of Alzey was a favoured place of residence for the Palsgraves during the time of both Ruprechten, Ruprecht ll and Ruprecht lll. who was King Ruprecht I of Germany from 1400 - 1410.
In the 15th and 16th centuries the castle was built into a representative castle complex which was badly destroyed during the Palatine War of Succession. As a result of the romantically inspired castle restoration movement of the 19th century, the ruin was rebuilt and restored to its historical splendour at the beginning of the 20th century. Since this time it has been used as the district court house.
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.
