The Wasserkirche, water church, is on the banks of the Limmat - but still, why the name? Actually, it was on an island in the river until the Limmatquai was built in 1839. Dating at least from the 10th century, what you see today is late Gothic style from the 15th century. See also the stained glass windows by Augusto Giacometti in the choir and the crypt with tombs almost as old as the church. A statue of forbidding Huldrich Zwingli stands at one end. Under the stone arches outside, the Kunstkiosk (art kiosque) sells books and prints and street musicians set up shop. If you get lucky you’ll hear the accordionist who gives masterful Bach recitals. Helmhaus gallery in the same building.
