Neugebäude Palace is a large Mannerist castle complex in the Simmering dictrict of Vienna, Austria. It was built from 1569 onwards at the behest of the Habsburg emperor Maximilian II on the alleged site of Sultan Suleiman's tent city during the 1529 Siege of Vienna and apparently modeled after it.
It fell into disuse already in the 17th century and today stands in ruins. Under monumental protection since the 1970s, there are various efforts to restore the site.
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.
