Town wall

Commonly known as the Star of the Sea, after an old title for the Virgin Mary, this Romanesque church was largely built in the 11th and 12th century. Although no archaeological research has been carried out, historians believe earlier churches stood on the same spot before. Large parts of the church treasures were lost when the city became part of the First French Republic. The church was then used as a blacksmith workshop by the military, and the cloister area served as stables. The basilica's two narrow towers, topped with marlstone turrets, make it an important landmark for Maastricht and the charming little chapel is a popular place with both locals and tourists to light a candle. Inside, the miraculous statue of Our Lady, Star of the Sea is perhaps the main attraction.

Before the restoration of the Derlon Hotel started, Maastricht's city archeologists undertook an extensive survey of the site. The Roman finds, from the 2nd, 3rd and 4th century, are considered that important that it was decided to conserve them and exhibit these to interested parties. The following can be seen in the cellar of Derlon Hotel: part of a 2nd and 3rd century sanctuary (including a Jupiter column), a 3rd century well, part of a pre- Roman cobblestone road and sections of a wall and a gate dating from the 4th century.

The museum outlines the natural history of southern Limburg. Modern displays offer an insight into both the recent and distant past. Among the museum's highlights are the remains of enormous Mosasauriers and Giant Turtles found in limestone at the St Pietersberg caverns. Fossils of all shapes and sizes show how South Limburg has changed in the course of the last 300 million years.

This is the city library and an exhibition space for archaeological finds and Maastricht pottery.
