Not to miss

Bonnefantenmuseum

The Bonnefantenmuseum features a 28m tower that's now a local landmark. Designed by Aldo Rossi, the museum opened in 1995, and is well laid-out with collections divided into departments, each on its own floor: Old Masters and medieval sculpture are on one floor, contemporary art by Limburg artists on the next. A dramatic sweep of stairs beckons visitors to both floors.

Space is devoted to special exhibitions and shows, of which there are usually four annually, two following classical/historical themes, two on more contemporary material. It also espouses an ongoing commitment to solo exhibitions by young and emerging artists, and is the patron of the major biannual Vincent Van Gogh Award for Contemporary Art in Europe. Temporary exhibitions are revelatory, such as the recent 'Travellin' Light' show, focusing on Dadaist lineages.

Sint Pietersberg Tunnels

Much of Maastricht is riddled with defensive tunnels dug into the soft sandstone over the centuries. The best place to see old tunnels is Sint Pietersberg, a Roman fort 2km south of Helpoort. This is a really beautiful area, pastoral and peaceful - the fort is an arresting sight peeking over the charming hillside - and it's a very relaxing walk from town. If you must, take bus 29, which goes past the fort from Vrijthof.

The Romans built the Northern Corridor System Tunnels throughout the hills over a period of 2000 years; at one stage, the tunnels extended under the Netherlands-Belgium border. Thirteen species of bats have been found living below the surface.

Vrijthof

Vrijthof is the heart of the city, a large square surrounded by lively cafes and photogenic churches. It's dominated by Sint Servaasbasiliek (Basilica of St Servatius), a pastiche of architecture dating from the 11th century. Sint Janskerk, a small 17th-century Gothic church, is one of the most beautiful in the country. Climb to the top for gorgeous views.
