The Reformed Church at the heart of Klosters village is the oldest surviving building in the settlement and the origin of the village's name. Klosters takes its name from a medieval Augustinian monastery founded here in the 13th century; after the Reformation the monastic buildings were converted and the church survived in modified form. The current structure dates largely from 1681, with subsequent renovations, and retains a simple interior characteristic of Swiss Reformed churches.
The church sits on a small rise in the village centre, visible from most approaches and surrounded by an old churchyard. It is not typically open for casual visits but can be viewed from outside, and the surrounding lanes between the older timber-frame buildings make for a pleasant short walk. The church sees regular Sunday services and occasional concerts in summer.
