This is the Wrocław Cathedral, a landmark in the city of Wrocław, Poland. The cathedral has been through many wars, and has thus been damaged and repaired as many times. The details of it standing the test of time can be found here. Today, the church houses the largest pipe organ in Poland, which used to be the biggest in Poland at one period of time.
The stamp on the left is a Christmas stamp issued on 30th November 2012. It is one of a set of 2 Christmas stamps. I love Christmas themed stamps!
