The Czartoryski Palace is a palace in the town of Pulawy, whose origins date back to the second half of the 17th century and are related to the history of the magnate families: the Lubomirski, Sieniawski and, above all, the Czartoryski family.
It was first built between 1671 and 1679 by Stanisław Herakliusz Lubomirski to designs by the Dutch architect Tylman van Gameren. This complex included a garden. The town had passed to the Sieniawski family by 1706, when the palace and its surroundings were destroyed by Swedish troops during the Great Northern War. Reconstruction began under Elżbieta Sieniawska in 1722. Soon afterwards Maria Zofia Czartoryska married August Aleksander Czartoryski and between 1731 and 1736 they built a new Rococo palace on the site, to designs by Jan Zygmunt Deybel.
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.
