The Grand Pipe Organ was built in 1648 and renovated in the 19th century by Friedrich Haas and again in 1972/1977 by Orgelbau Kuhn in Männedorf. The 5,945 pipes are distributed across 84 registers and are arranged in slider chests of 5 manuals and pedals. A unique feature is the rain machine in the echo chamber in the attic of the church. The largest pipe, cast in 1648, is 10 meters long and weighs 383 kg.

From here you have an excellent view back towards the pipe organ.
