The St Servaaskerk is a church devoted to St Servaas. The church dates back to 950, and was built on the site where he was buried in the year 384. Of the original construction, only the crypt and tomb remains. The rest of the building is now of medieval construction, with a Gothic cloister and treasury, which holds numerous religious artefacts dating from 890 onwards, including copperwork and crucifixes. Other interesting parts of the church include the 13th century Bergportaal which was used as the main entrance during services.
