Heilig Kreuz (Holy Cross) Monastery was founded at the end of the 12th century by Dietrich the Oppressed, Margrave of Meißen. It was for the Benedictine nuns. Its buildings were initially located between Burgberg and Elbe on the site of a former moated castle (today's Leipziger Strasse 30 to 40).
In 1217 the monastery was relocated to the left bank of the Elbe, approx. 1.5 km north of the old town of Meißen. A church building was erected in the first half of the 13th century.
After Reformation, the monastery was closed in 1568. The monastery building itself was left to decay and finally destroyed in the Seven Years' War (1756–1763). From 1945 the site of the monastery served as a garden center. Since 1994 it has been the seat of the Meißner Hahnemannzentrum e. V., which had security work carried out on the buildings.

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.
