Maidla manor (Wrangelstein) traces its history back to at least 1465, although the village is mentioned for the first time as early as the 13th century, in the Danish Census Book. The manor estate has over the centuries belonged to several different aristocratic families. The present baroque manor house was built in 1764-1767 according to plans by architect J. P. Dürschmidt, during the ownership of the Wrangel family. After the Estonian land reform that followed the declaration of independence of Estonia in 1919, the manor was converted into a school. The manor is a fine example of baroque manor house architecture in Estonia. Details such as the finely carved door, interior stucco decoration and the pediment decorated with coats-of-arms, survive.

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.
