The Citadel of Dinant (Citadelle de Dinant) was built in 1815 on a site which was originally fortified in 1051 when the region was ruled by the Prince-Bishopric of Liège. The citadel overlooks the city of Dinant and the strategic Meuse river which runs through the town. It is open to the public.
Together with Huy, Liège and Namur, the Citadel of Dinant forms part of the so-called Meuse Citadels.
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.
