The National Museum in Kraków, established in 1879, is the main branch of Poland's National Museum, which has many permanent collections around the country. Kraków National Museum was first housed at the upper floor of the Renaissance Sukiennice building, now the home of one of its many divisions. The construction of the Museum's New Main Building at 3 Maja Street started in 1934, but was interrupted by World War II. It was completed only in 1992. During World War II the collection was looted by German soldiers. After the war the Polish Government retrieved many of the works seized by the Germans. Still more than 1.000 artefacts are missing, including The Fight Between Carnival and Lent by Pieter Bruegel the Elder.
