The Premonstratensian abbey in Middelburg was founded in 1127. Most of the buildings were destroyed by fire in 1492 and 1568. Today there are two adjacent churches, Koorkerk and Nieuwe Kerk. The Nieuwe Kerk dates from the 16th century, with the nearby Koorkerk abbey church dating from the 14th century. The octagonal tower, known as Lange Jan (Tall John), also originally dating from the 14th century but unfortunately has burned down several times. Its 91m height dominates the city but is difficult to photograph because of the surrounding buildings.
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.
