Construction on St. Peter’s Church began in the middle of the 14th century and was not finished until the early 1400s. The most prominent feature is this 380 foot spire. The tower was added during the late 16th century. A quick tour inside of the basilica is interesting. However, many tourists claim the best part of Petrikirche is the 147 foot observation deck. If you are ambitious and physically fit, you can climb the 196 steps. Or for a small fee you can take an elevator to get a bird’s eye view of the city.
