Purdi manor (Noistfer) has a history that goes back to at least 1560. The current building is a baroque manor house, built in circa 1760-1770 by the von Baranoff family. Some baroque interiors still survive. Additions to the building were made in the 19th century. Several annexes belonging to the estate are still preserved, notably the granary, as well as the baroque burial chapel of the Ungern-Sternberg family, who were the last feudal landlords of the estate.
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.
