This is the cathedral in Gniezno, historically one of the most important churches in Poland. Gniezno was the first capital of Poland, starting with the politically-motivated christening of the King Mieszko in the 10th century.
The cathedral was established at this location in 11th or 12th century, and experienced a number of fires and mishaps over the centuries.
In 1809, the French army installed a military warehouse in the Cathedral which was removed when Napoleon's troops left the area. In 1939, following the invasion of Poland, the Germans converted the temple into a concert hall. In 1945, a fire broke out caused by the intentional incendiary artillery shelling by the Red Army.
