Genovevaburg is a castle standing on the southwestern side of Mayen in the German state of Rhineland-Palatinate. The castle is the symbol of Mayen and has been rebuilt several times since first being destroyed in 1689. Its name comes from a legend, according to which the seats of counts palatine, Siegfried and his wife, Genevieve of Brabant (German: Genoveva), were supposed to be on the same hill in (or above) Mayen. The earliest references linking the legend to this region date to the 17th century. Since when the castle and its bergfried, the so-called Golo Tower (Goloturm), have been linked to the legend is unknown.
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.
