Like the rest of the Old City, the Palace Square was almost completely destroyed by the Nazis, but after the war, between 1947 and 1957, it was rebuilt from its ruins. Like many squares in Europe, the square is now beautifully decorated, with all its homes painted in a variety of colors. At the entrance to the square on the left, adjacent to the continuation of the wall of the Old City, you will see a temporary exhibition on the reconstruction of the square from the destruction of World War II.
If you wish, you can go up to the observation tower from the church tower. This is not a very difficult climb, about 150 steps. The panoramic view from above is beautiful and worth the effort.
Pay attention to the Red Building in the square, which is the Royal Palace of the kings of Poland. The king of Poland did not always live in Warsaw. It was King Sigismund III (Wassa), who in the 16th century transferred the capital from Krakow to the city of Warsaw. The statue of the King Sigismund you will see stands on a high pillar in the square and looks out at his palace.
And by the side of a palace, you can see the change of guard every hour.
