Start at the St. Paul's Cathedral. Built in the 10th century, the construction of the Gothic church didn’t finish until six centuries later. It owns many remarkable works by major Belgian artists, including its 16th-century stained glass windows and the magnificent Reclining Christ dating from 1696 by Jean Del Cour. Also, visitors can get immersed in the tranquility and serenity of the temple in the pleasant garden enclosed by the adjoining cloister.

Palais des Prince-Eveques (Palace of the Prince-Bishops)

Next, walk by the Palace of the Prince-Bishops, a historic building situated on Saint-Lambert Square. The former residence of Prince-Bishops now hosts law courts and houses the provincial headquarters. Despite its imposing Italian Renaissance façade, the palace bears an evident Gothic influence. Interestingly enough, its series of courtyards are surrounded by plenty of columns richly decorated with extremely peculiar patterns.
