Wiedersberg Castle was built around 1200 to protect the route from Plauen to Hof. The first documentary evidence dates from 1267. The castle is considered the ancestral home of the barons Wiedersperger. The castle was expanded after 1300 and fell into disrepair from 1500. In the 16th century, a mansion in the Renaissance style was built in the valley in the local area. Today the ring wall and gate tower remain, as well as some vaulted cellars and the surrounding walls. The double neck ditch carved into the rock and the gate drive of the gate tower, which swings around 90 degrees in the tower, are remarkable.
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.
