The Romanesque Sint-Servaasbasiliek (Basilica of Saint Servatius) is built on Saint Servatius - an Armenian missionary who died in Maasticht in the year of 384 -gravesite. It is likely that the current building is the 4th iteration of churches on this site. The first church was a small memorial chapel, which was replaced by a larger church. Next, a pilgrim church was built. Finally, the current church was built between the 11th and 12th centuries.

The Sint-Servaasbasiliek is considered being the oldest still standing church in the Netherlands. The large, triple-nave transept basilica was built largely in Romanesque style, using millstone grit and marl. The church building serves as a parish church of the Roman Catholic St. Servatius parish and deanery church of Maastricht.

Since 1985, the church has held the title of minor basilica. The church, the cloisters, and the treasure room are open to the public and can be visited.
