‘Alter Peter’ is the tower of the St. Peter’s church and has an observation deck at the top. Awesome view and a free leg workout for just 5€ (3€ for students)!
There are about 300 steps which you’ll need to climb. But once you get to the top, you have an outstanding view over Marienplatz and the centre of Munich.
When the weather is great it can get quite crowded and the queue will be a little longer (last time I went there in Summer 2023, wait was about 15 mins at the entrance).
Bonus: Glockenspiel 🔔
Daily at 11:00 and 12:00 (and at 17:00 from March until October), the ‘Glockenspiel’ (a Carillon) starts in the tower of the New City Hall (Neues Rathaus) at Marienplatz – right across from Alter Peter.
Four different songs can be heard to which the figurines start moving. The program changes monthly.
See the video below for an example from last time I went up to see it 👇
