The oldest remaining part of this castle is the 15th century southern tower. Much of the rest is from the 17th century. On the northern side you can see a bit of the moat that once surrounded the castle.

A reconstruction of the Atuatuca Tungrorum temple where it originally stood. Given that it's outside the Roman city walls, and the temple stood there before the walls, it's probable that it originated as a pre-Roman place of worship.
Kasteel van Rooi
Originating in the 14th century, this castle has also been modified over the centuries. For example, the whitewashed northwestern façade got its current appearance in 1698, as the inscription reads. A farm was built on the premises in the 17th century, of this only the gate and a barn remains.
Standbeeld van Ambiorix
Completed in 1866, this statue depicts the fearsome leader of the Eburons, which was a tribe that defeated two of Caesar's legions in 54 BC. He is shown trampling a laurel wreath and Roman banners while wearing Celtic clothes and carrying a battle axe and a sword. Nowadays Ambiorix is one of the most famous characters in Belgian history.
Perroen
All of the "good cities" of the principality had one of these monuments; a stone pillar with a cross-bearing orb on top standing on a set of stairs. First occupying the place where the Ambiorix statue now stands, it was first moved in 1886 and has been on its current place since 1985.
Standhuis en belfort
Originally at Grote Markt, the town hall was burned together with the rest of the city in 1677. It was built between 1737 and 1750 in bricks in classical style, inspired by the city hall of Liège. The front pediment has a coat of arms of Georges-Louis de Berghes, the Prince-Bishop of Liège at the time. The building is not open to visitors.
