The church & the biggest organ in Switzerland
The giant church of the benedictinian monastery is really worth a visit and it is open for visitors during the day for free entry. The baroque interior shows wonderful paintings on the walls and the ceiling and I liked especially the ornate chandeliers, you can see one of them in my 2nd photo. The organ of this church is the biggest organ in Switzerland, including 137 registers.
