The royal castle was built between 1589 and 1619 as the residence of King Sigmund III of Poland. The castle was destroyed by the Germans during World War II and was rebuilt in the same way between 1971 and 1984. Today the castle is a cultural center and houses an important museum of Polish heritage and culture. It is a special place in order to learn a lot about the country's past and what this ancient city has gone through. In addition, it is a beautiful and charming place for tourists when they visit Warsaw.
