Place Saint-Lambert, Central square in Liège, Belgium

Place Saint-Lambert is a central square in Liège featuring multiple levels and several buildings, including the Palace of Justice and Provincial Palace positioned on its upper section. A major bus station occupies the lower section, connecting different parts of the city through regular transit services.

A cathedral dedicated to Saint Lambert stood on this site until 1794, serving as a major religious building in the city. The archaeological remains of this cathedral are now preserved in the underground Archéoforum museum, where visitors can see traces of the earlier structure.

The square takes its name from the cathedral demolished in 1794; the name was officially given in 1827, and the last rubble was cleared in 1829. Each year on the fourth Sunday of April, the professional cycling classic Liège–Bastogne–Liège starts here. On 24 July 1919, the city received the Légion d'honneur on this square, in the presence of President Raymond Poincaré, Marshal Ferdinand Foch and King Albert I.

The square spans multiple levels, so it helps to move gradually through different elevation zones to fully explore the space. The lower section with the bus station can be busy and noisy, so quieter areas can be found on the upper levels near the palaces.

The Archéoforum under the square displays traces of more than 9,000 years of occupation: occasional Neolithic presence, a Gallo-Roman villa, a village from the time of Lambert of Maastricht's assassination, and the successive cathedrals. The foundations of the former cathedral were found during several archaeological investigations.
