The Dominican Monastery in Ústí nad Labem was founded in 1186. The church was remodelled in Baroque style in 1718-1722 during extensive reconstruction designed by Litoměřice architect Octavio Broggio. At the wish of the Prior of Ústí, he based his design of the St Adalbert Church on the model of the Prague Church of St Ursula. Under the communist regime it was used for storage and later on, whitewashed and stripped of all furnishings, converted into an exhibition hall. The wall paintings from 1928 were probably by Albin Müller. The original monastery was a single-wing structure at first (in 1617-1650), its enlargement being impossible for financial and political reasons, the second wing was added during the Baroque reconstruction. The south wall of the church and monastery merges with the city walls.
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.
