The church's interior is adorned with impressive frescoes, sculptures, and a grand high altar, making it a treasure trove of religious art.
One of the most notable features of St. Peter's is its tower, affectionately known as "Old Peter." Visitors can climb the 299 steps to the top for a panoramic view of Munich, including a stunning perspective of Marienplatz and the Frauenkirche. The church has survived multiple reconstructions, particularly after World War II, and remains a beloved landmark that reflects Munich's rich historical and cultural heritage.
