Partially standing over the River Limmat, Rathaus is the city hall of Zürich. It occupies a prominent position in the heart of the old town, on the right bank of the river. The Baroque-style edifice was built in the late 17th century by the architect, J.H. Holzhalb, as a replacement to an older mediaeval structure, originally serving as the seat of the government of Republic of Zürich.
Zurich's 17th century town hall is located right on the Limmat River. It wasn't open when we were there but if you are there on a Tuesday, Thursday or Friday it is open to the public from 10am-11:30am, admission is free.
