The square sits on land confiscated during the French Revolution, which led to the demolition of the original Franciscan convent.
A significant archaeological excavation in the 2010s uncovered the foundations of the medieval monastery and defensive walls.
The equestrian statue of William II was unveiled in 1884 to celebrate the personal union between the Netherlands and Luxembourg.
The square's nickname 'Knuedler' is a remnant of the Luxembourgish word for the knot in a monk's belt.
The municipal administration office (Hôtel de Ville) has occupied the site since the 1830s.
Place Guillaume II, locally known as the Knuedler, is the largest open-air public square in Luxembourg City, situated on the site of a former 13th-century Franciscan monastery. The name 'Knuedler' derives from the knotted rope worn by the Franciscan friars who once inhabited the cloister. The square is dominated by an equestrian statue of William II, King of the Netherlands and Grand Duke of Luxembourg, created by Antonin Mercié. The Town Hall (Hôtel de Ville) stands at the western end of the square, serving as the official seat of the municipal administration. Beneath the square lies a large subterranean parking facility and historical remains that have been excavated during various urban renewal projects. It functions as the central social hub for the city, hosting weekly markets, outdoor concerts, and the annual Summer in the City festivals. The square features a prominent bronze sculpture of the Luxembourgish poet Michel Rodange. Surrounding buildings represent a mix of neoclassical and late 19th-century urban architecture.

Visit on Wednesday or Saturday mornings to experience the traditional weekly market selling local produce and crafts.
Check the municipal calendar for the 'Summer in the City' concert series held directly on the square.
Look for the smaller, more discreet monuments dedicated to local cultural figures tucked near the perimeter of the square.
Avoid assuming the square is only a parking lot; the surface area is primarily for pedestrians, while vehicles are directed to the underground structure.
The square is public and open year-round, though it may be restricted during major municipal events or public celebrations.
