The municipal administration’s proud main building today is comprised of four formerly separate buildings: the chancellery, armoury, town hall and town house.

In the 18th century, the three Protestant Estates of Zurich, Berne and Glarus exchanged this building for their chancellery building on the Rathausgasse and commissioned architect Franz Anton Schwarz from Bremgarten to convert it into a new local records office. During the period of the revolution, the building reverted temporarily into private hands, but since 1892 it has been owned by the municipality and is the seat of the municipal government. It was renovated on the outside in 1918, 1969/70 and in 2013. In 1997/98 the interior was modernised by Baden architects Zulauf und Schmidlin. The Stadthaus has been declared a Swiss listed building.

On the second floor is the meeting room of the old Confederation, with a polychrome ceiling with beams, and with copies of the glass panels painted by the Zürich glass painter Lukas Zeiner, donated by ten towns in 1500 and sold in 1812.
