St. Mary's, the chief parish church in Prenzlau, is a High Brick Gothic building with a three-aisled hall and three polythagonal chapels on the church's eastern site. St. Mary's dual towers dwarf the town; the legendary gables featuring elaborate tracery are worthy of a cathedral. Excavations have shown that this replaced an earlier church on the site (1235-1250), a vaulted three aisled hall church with a transept and an elongated right-angled ambulatory built from loose fieldstone.
The church was almost completely destroyed in April 1945, with a fire destroying all but the enclosure wall. However, the church's Arcardian pillars featuring rounded arches and (most importantly!) the ornate gables and elaborate tracery on the eastern side of the building survived the fire. Construction work aimed at rebuilding the church as been underway since 1970; the artistic decoration in the church's interior is currently being restored. Despite the ongoing work, the church is home to large concerts that bring together the architectural appreciation of the unique heritage site with the pleasure afforded by live music.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
