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.
References:The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
