Château de Buchenek is a castle in the commune of Soultz-Haut-Rhin. Dating from the second half of the 13th century, it was altered, possibly in the 14th century, and in the 16th century.
The castle was first recorded in 1251. The logis, of a rectangular plan, possibly still dates from this period at the lower level; it was altered in the 14th century (there is evidence of building work) as well as in the second half of the 16th century (staircase tower). Restored after the Thirty Years' War, the castle was sold as national property. In the 19th century it was used as a factory. Bought by the town in 1976, the castle has had a significant restoration and, since 1990, has housed the municipal museum.
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.
