Dynge Castle, also Dyngehus as it was once called, was a Norwegian fortified castle in use from approximately 1250 and onwards towards the beginning of the 16th century, when it burnt down. Located in central Bohuslän, since then passed into Swedish possession, the castle was mentioned several times in Norwegian records. The site was excavated 1912-1913 by Wilhelm Berg, who had also excavated the contemporary and largely similar castle Ragnhildsholmen Castle during the 1880s, and Olsborg Castle. Since then, the site has had no closer examination by archaeologists.
The castle was in shape similar to a motte-and-bailey, with a stone keep surrounded by a small moat, standing on top of a cliff overlooking Gullmarsfjorden. The foundations of the central keep's walls remain clearly visible, as does the moat. It is one of few remaining medieval structures in Uddevalla Municipality, alongside Dragsmark Abbey and Bokenäs Old Church.
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.
