The current Præstø Church was built in the mid-1400s to the site of earlier church. There was also a monastery from the end of 1200s to Reformation (1530s). Abbey buildings were demolished in 1563. The finest detail in the church is an altar donated by Laurits Nielsen in 1657.
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.
