Teplá Abbey is a Premonstratensian abbey in the western part of Bohemia, included in the Archdiocese of Prague. It was founded in 1193 by the blessed Hroznata, a Bohemian nobleman (d. 1217). The first monks came from the Abbey of Strahov in Prague.
The present monastery building was erected by Abbot Raimund Wilfert II (1688-1724); the library was built by Abbot Gilbert Helmer (since 1900). The Romanesque church, with additions in the style of the transition to the Gothic, is one of the oldest churches of Bohemia. The high altar of the church was sculpted by Josef Lauermann and Ignatius Platzer in 1750. After Hroznata was beatified in 1897, his reliquary casket was moved to the apse of the church for display. The original burial place of Hroznata is marked by on the floor before the main altar, where his original sarcophagus also stands.
Plenteous monastery activity is shown in the literature that is defined by its rich collection of prints of different nature in the monastic library.
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.
