Arlon is the southernmost city in Belgium, tucked into the corner where Belgium meets the Grand Duchy of Luxembourg. A small town of around 24,000 people, it has preserved a quiet charm, with old houses in the historic centre built in either the typical Luxembourgish style or the Belgian neo-classical fashion of the late 19th century.
The name comes from the Latin Orolaunum, and the city's Roman roots are its main draw. The Musée Luxembourgeois has a remarkable collection of archaeological finds, including over 450 Gallo-Roman sculptured panels and statues from tombstones and Roman thermae that give a vivid picture of daily life two thousand years ago.
The Archaeological Park on Rue des Thermes Romaines is worth a visit. At its centre are the foundations of a 5th-century basilica — claimed to be the oldest church in Belgium — surrounded by a Merovingian cemetery from the 6th century, with many original tombstones still in place. At the back of the park you can see the remains of Roman baths.
