Apart from the Warsaw Old Town area, reconstructed after World War II, each borough has something to offer. Among the most notable landmarks of the Old Town are the Royal Castle, Sigismund's Column, Market Square, and the Barbican. Further south is the so-called Royal Route, with many historical churches, Baroque and Classicist palaces, most notably the Presidential Palace, and the University of Warsaw campus. The former royal residence of King John III Sobieski at Wilanów is notable for its Baroque architecture and eloquent palatial garden.

Nearby is the Okopowa Street Jewish Cemetery, one of the largest Jewish cemeteries in Europe. In many places in the city the Jewish culture and history resonates down through time. Among them the most notable are the Jewish theater, the Nożyk Synagogue, Janusz Korczak's Orphanage and the picturesque Próżna Street.
