The Emmaus monastery is an abbey established in 1347 in Prague. The area became the only Benedictine monastery of the Bohemian kingdom and all Slavic Europe.
In the 1360s, the Cloisters of the Monastery were decorated with a cycle of 85 wall Gothic paintings with parallels from the Old and New Testaments. The Gothic cloisters also feature original faded frescoes with bits of Pagan symbolism from the 14th century. The monastery was baroquized in the 17th-18th centuries and the two temple towers were added.
Charles IV gave to the just-founded monastery the manuscript Reims Gospel, it was probably lost from Prague in the time of the Hussite Wars, manuscript later became part of the Reims Cathedral treasury. The monastery became a center of culture and art, students of Cyril and Methodius studied there in addition to Jan Hus.
During the World War II the monastery was seized by the Gestapo and the monks were sent to Dachau concentration camp. The monastery building and vaults were destroyed by a U.S. bombing raid on Prague on 14 February 1945. The modern roof with steeples was added in the 1960s. It was returned to the Benedictine order in 1990, the monastery currently belongs to three monks, two of whom live there.
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.
