The Magnuskirche is a small church in Worms, to the south of Worms Cathedral. It is the city's smallest church. Archaeological evidence and its dedication (probably identifiable with Magnus of Füssen, a Carolingian saint) suggest it originated in the 8th century - part of that building survives in the nave's north wall.
The first written record dates to 1141. It was enlarged many times between the 10th and 15th centuries and during that era served as the nearby Andreasstift's parish church. It is the oldest Lutheran church in south-west Germany, since Martin Luther stayed in it and preached in it during the 1520 Diet of Worms. After the severe damage to the city in 1689 during the Nine Years' War, the church was restored in the Baroque style in 1756. It was destroyed by Allied bombing on 21 February 1945 and restored again in 1953.
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.
