The electoral hunting lodge Breitenbrunn (Jagdhaus) in the Ore Mountains community of the same name was converted from a watchtower, which was probably built in the 13th or 14th century, is now a ruin under monument protection and is a landmark of the place.
After a Vorwerk of the Schwarzenberg rulership was first built and later a settlement was built, the watchtower was converted into a hunting lodge, accommodation and storage for hunting utensils. The building, which was also used as the forester's house, burned down in 1610, including the newly added third floor and added Wendelstein, and in 1617, was rebuilt and fell into ruin, apparently unused, after 1700.
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.
