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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
