Right on the edge of Marienplatz is Altes Rathaus, or the Old Town Hall.
To me, it looks like a combination of a small castle and a church.
It is large. And beautiful. It now houses governmental offices, so nothing much to see insides. But as you can see from the picture, tours commonly start from this location – probably because it’s easy to find.
I think the tower is one of the best features of the building. It is very Bavarian.
