The National Museum in Gdańsk (Muzeum Narodowe w Gdańsku), established in 1972 (although the history goes back the third quarter of 19th century), is one of the main branches of Poland's National Museum system. Its main location is in the old Franciscan monastery, which has been used to house exhibits since the end of the 19th century. Currently the museum has seven departments.
The first floor is given over to paintings, with a section devoted to Dutch and Flemish work. The jewel of the collection is Hans Memling's (1435-94) triptych of the Last Judgment, one of the earlier works of the artist, dating from 1472 to 1473. You'll also find works by the younger Brueghel and Van Dyck, and the beautifully macabre Hell by Jacob Swanenburgh, who was the master of the young Rembrandt.
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.
