The landmark of Příbram and the most valuable monument is Svatá Hora (literally 'Holy Mountain'). It is the oldest and most important Marian pilgrimage site in Bohemia, protected as a national cultural monument. It consists of a Baroque monastery complex, cloisters and chapels. The cult of the statue of Saint Mary of Svatá Hora began in the 14th century, when, according to legend, it was carved by Bishop Arnošt of Pardubice himself. In 1647, a chapel on the hill Svatá hora was acquired by the Jesuits, who had rebuilt it to a magnificent temple in 1658–1675. This Basilica of the Assumption of the Virgin Mary of Svatá Hora was built according to the design of the architects Carlo Lurago and Benjamin Schleyer, and decorated by Jan Brokoff, Petr Brandl and other famous artists. Next to the basilica is a Baroque residence. The complex is connected to the town by a 450 m long staircase from 1685, which was roofed in 1727–1728, and Kilian Ignaz Dientzenhofer also participated in the final form.
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.
