Château de Larressingle was built in the second half of the 13th century. The second and third floors were added by Arnaud Orthon de Lomagne, Bishop of Condom, between 1285 and 1305. Windows were added at various times in the 15th and 16th centuries, particularly between 1521 and 1545 when extra works were carried out for Monseigneur de Grossolles, including the construction of a hexagonal tower.
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.
