Surrounding Krakow's Old Town, Planty Park stretches about 2.5 miles (4 km) and covers 52 acres. It was established in the early 19th century to take the place of the Old Town walls after they were destroyed. The park is really a chain of gardens designed in different styles, connected by walkways and lawns and topped off with a variety of fountains and sculptures.
Walking through Planty Park is like walking through Krakow’s history. You will pass a small segment of the old walls, as well as the 13th-century Gothic-style Florianska Gate and the Barbakan, a defensive fortress dating to 1499. Other notable landmarks include a Carmelite monastery that was once used as an Austrian prison, the 17th-century bishop’s palace from whose window Pope John Paul II once greeted the residents of Krakow and the Church of the Snowy Mother of God, built in 1635. More modern structures along the park are the art nouveau Palace of Art and the Bunkier Sztuki, a concrete exhibition hall that has been transformed into a museum and bar.
Allow an hour or two to walk around the entire park. Admission is free, and while you can enter anywhere, the most interesting route may be to start at the base of the historic Wawel Castle and go from there.
