This is a new UNESCO whs for my collection thanks to dear Rafal :) The "guilty" one for the continuing Slavic RR addiction :)
The Castle in Malbork was built in Prussia by the Teutonic Order, a German RomanCatholic religious order, as an Ordensburg. The Order named it Marienburg, literally "Mary's Castle". The town which grew around it was also named Marienburg, and since 1945 it is known as Malbork. The castle is a classic example of a medieval fortress, and is the world’s largest brick gothic castle. UNESCO listed the castle and its museum asWorld Heritage Sites in December 1997. It is one of two World Heritage Sites in the region with origins in the Teutonic Order. The other is the Medieval Town of Toruń, founded in 1231 as the site of the castle Thorn.
the stamp is also a nice one (well its blue :)), issued in 2007 for the 750th Anniversary of the Foundation of Cracow and shows the Coat of Arms.
Thanks a lot Rafal :)
