Heinfels castle stands in the Puster Valley, near the entrance to the Villgraten Valley. Although the town was first settled by Huns around 500 AD, a castle was not mentioned until 1243. It belonged to the County of Gorz, and was expanded on the west side in 1500. In 1526, it was besieged by Michael Gaismair and 2,000 soldiers seeking to overthrow Catholic rule in the area. Today it is privately owned.
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.
