St. Mary's Church, also called Mariakerk or Maria Maior, was one of five collegiate churches in the Dutch city of Utrecht, the others being St. Martin's Cathedral, St. Salvator's Church, the Pieterskerk, and the Janskerk. It dated from the eleventh century and was considered one of the finest buildings in Romanesque style in the Netherlands. The church was demolished in stages during the first half of the nineteenth century. Today only the cloister at the Mariaplaats remains, behind the Gebouw voor Kunsten en Wetenschappen which houses the Utrecht Conservatory.
