Walking down Krakowskie Przedmiescie Street (Royal Route) you can pass many important sites. In St. Anne’s Church you can climb up its tower to the viewing terrace from which you can see the entire Old Town. Then, you can pass the Presidential Palace. It hosted the authors of the Constitution of May 3, 1791 (the first modern constitution in Europe and second in the world). You can stand in front of the main gate to the largest university in Poland – the University of Warsaw and you can hear stories about the famous Polish atronomer – Nicolaus Copernicus standing next to the Copernicus Monument. From there you can proceed to the Holy Cross Church – a beautiful Baroque building where the heart of Frederic Chopin is still beating.
