Located between the German and Belgian borders, Maastricht is one of the most delightful cities in the Netherlands. It is a cosmopolitan city where the three languages coexist, and also one of the oldest towns in the country. The busiest of Maastricht’s many squares is Markt, with the mid-17th century Stadhius at its center. The casemates in Waldeck Park are evidence of the city’s once-impressive fortifications. Of the two ancient defensive tunnel systems under the hill of St. Pietersberg, the Zonneberg is the better one, situation on the far side of the hill at Casino Slavante. Just outside the city lies the busy tourist town of Valkenburk, which provides a starting-off point for walking to the nearby hills and forests. Across the river is the city’s main art gallery, the Bonnefantenmuseum, with a collection ranging from old masters to contemporary artists. The building was designed by Aldo Rossi, is located in the newest part of Maastricht known as Ceramique, and is an attraction in and of itself.
