Prince-Bishops' Palace, Medieval palace in central Liège, Belgium

The Prince-Bishops' Palace is a stone palace on the Place Saint-Lambert in Liège, with a dark slate roof and a central curved pediment carved with a coat of arms flanked by two lions. A square clock tower with a spire rises above the roofline. The rusticated ground floor and two upper floors of tall windows are topped by a balustrade, and a balcony with three flags sits above the arched entrance. It now houses the Palace of Justice and provincial services.

A first palace, integrated into the city walls, was built around 1000 by Prince-Bishop Notger and burned in 1185. Its successor, rebuilt under Rudolf of Zähringen, was badly damaged in the Burgundian sack of 1468 and burned again in 1505. Érard de La Marck then had Arnold van Mulken build the present palace from 1526, finished by the end of the 16th century; the south facade was redone after the 1734 fire, and a neo-Gothic west wing followed in 1849.

The palace served as the residence and power center of Prince-Bishops who held both religious and political authority over the region for centuries. Its layout and decoration reveal how important leaders combined spiritual and secular roles in a single institution.

The great courtyard with its 60 columns can be seen from the Place Saint-Lambert side, but the second courtyard is closed to the public except on rare occasions such as heritage days; it also serves as the passage for defendants escorted by police between cells and court services. A carillon of 18 bells above the entrance facing the square sounds every quarter of an hour.

The 2011 extension was not a new wing of the old palace but a set of separate buildings erected facing its western side, built to keep Liège's courts in the city centre after they had been scattered across about ten sites. The palace was also proposed in 2008 for UNESCO World Heritage listing and appears on Belgium's tentative list.
