An 11th-century Romanesque church that feels different from anything else in the Netherlands — older, more austere, built with a gravity that the later Gothic churches of the north never quite match. The westwork towers over the Onze Lieve Vrouweplein square, and the interior has a quality of stillness that the nearby Basilica of Saint Servatius, with its tourist traffic, has largely lost.
The Schatkamer (treasury) holds a collection of medieval art and liturgical objects, and the Star of the Sea chapel contains the celebrated statue of Our Lady of Maastricht, venerated here since the 12th century. The square outside is one of the most pleasant in the city, with good café terraces and a human scale that invites sitting.
