Work on building Haderslev Cathedral began in the mid-13th century. It was originally a large cross-shaped single-naved church built of bricks and granite cubes recycled from an older church. Only the original transept is still standing. The church nave was soon expanded to include three tall naves under one roof. This type of church is called a hall church. The present three-naved choir from 1400 is one of the most beautiful choirs from the Gothic period and has three incredibly tall 16-metre windows that allow the light to flood in. When South Jutland was reunified in 1920, the church was elevated to the status of a cathedral in the newly established Haderslev Diocese.
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.
