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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
