Catholic Parish Church of St. Gallus, Parish church in Wassen, Switzerland

The Church of Wassen, locally called s’Chileli vo Wasse, is the Catholic parish church of Wassen in the Swiss canton of Uri. Completed in 1734, it stands on a small rocky spur and is dedicated to Saint Gallus. Its altars come from the workshop of the Valais sculptor Jodokus Ritz and are marked by turned columns arranged in perspective, typical of Oberwallis and Uri Baroque. A circular funeral chapel from 1742 with an onion dome stands in front of the church.

A church at Wassen is documented from 1287 as a chapelry, and a dependent chapel is recorded in 1349 under Silenen; endowments by Katharina and Cueni Kluser followed in 1458, and an indulgence confirmed in 1480 attests the patronage of Saint Gallus. The present church was completed in 1734 and consecrated in 1742 by Franz Karl Josef Fugger, auxiliary bishop of Konstanz. Its altars come from the workshop of the Valais sculptor Jodokus Ritz (1697–1747).

Locals call it s'Chileli vo Wasse. The church appears in Emil Steinberger's 1976 sketch "De Traum vom Zugfahre", in the 2005 film of "Mein Name ist Eugen", and in the 2018 song "Chileli vo Wasse" by rappers Lo & Leduc, which stayed twelve weeks in the Swiss charts.

The church is located along the main street of the village and is easily accessible on foot. Visitors should note that as a sacred space, it can be entered only during services or at designated times.

Since the Gotthard railway opened in 1882, passengers see the church three times from different sides: the line climbs about 200 metres around Wassen through the Wattinger and Leggistein spiral tunnels, crossing the Meienreuss three times, with the first bridge below the church and the last some 200 metres above it.
