Bubenstein Castle (Ruine Bubenstein), also called Neu-Falkenstein, is a ruined spur castle on the northern side of the Höllental valley, about 500 metres west of Old Falkenstein Castle above the village of Falkensteig in the municipality of Buchenbach in the southwest German state of Baden-Württemberg.
The castle was built by Walter of Falkenstein in the 13th century and in 1266 its residents were recorded as the lords of Falkenstein. In 1328 the lords of Staufen were named as its occupants. In the 19th century, part of the castle rock was blown up for the railway line and in 1960 the castle was dismantled due to its poor state of repair.
The bergfried of the castle measured 10 by 10 metres, and the neck ditch was 5 metres deep and 8 metres wide. Of the old castle only wall remains and the neck ditch survive.
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.
