Jasov has the biggest monastery complex in Slovakia and its main church, dedicated to St. John The Baptist, is considered one of the country's most important late-Baroque buildings. Though the present complex dates from the 18th century, there has been a monastery since 1170. The first, probably made of wood, was destroyed by the invading Tatars in 1242. A Romanesque stone monastery soon replaced it and was rebuilt in a fortified style in the 15th century. The site was then completely levelled again in 18th century to make way for the present Baroque structure.
The current monastery was designed by the architect Anton Pilgram in 1766. The lavishly ornamented interior of the monastic church in Baroque style, the library of monastery, and conserved French garden are especially valuable. The monastery has 365 windows, 12 chimneys and four gates (representing the days, months and seasons of the year).
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.
