Luxembourg City Hall, Luxembourg

Luxembourg City Hall is the centre of local government, in which capacity it also houses the private office of the Mayor of Luxembourg City. Due to its position in Luxembourg's capital, the building regularly plays host to foreign dignitaries. It is located on the southwestern part of Place Guillaume II (Knuedler), the main square in the centre of the city. The two-story building features neoclassical style.

Until 1795, the Place Guillaume II was home to a monastery of Franciscan monks. At the time, Luxembourg's town hall was housed in the current Grand Ducal Palace, located just to the east of Place Guillaume II, on Krautmaart. The French invasion during the French Revolutionary War heralded the seizure of the monastery, and the beginning of the usage of the Grand Ducal Palace for central government purposes. As a result, for three decades, the municipal headquarters were moved around the city, without adequate accommodation.

Ever since Napoleon had given the site of the monastery to the city, plans had been underway to build a purpose-designed city hall, which finally came to fruition in 1828, when a design by Liège-based Justin Remont was given the go-ahead. The following year, the old monastery, which had fallen into disrepair, was deconstructed, with much of its material going into building the new city hall, the construction of which began in 1830. It continued through the Belgian Revolution, with Luxembourg City (protected by its German garrison) remaining the only part of the Grand Duchy outside the control of the rebel forces.

The building was completed in 1838 and first used as the seat of the city council, chaired by Mayor François Scheffer, on 22 October 1838. Due to the ongoing Belgian Revolution, the King-Grand Duke could not attend the City Hall opening ceremony. Consequently, the official unveiling had to wait until 15 July 1844, when William II also unveiled the equestrian statue to himself on the same Place Guillaume II (which is named in his honour). In 1848, the City Hall hosted the Constituent Assembly (from 29 April onwards), which wrote the new national constitution.

The building went without major changes until 1938, with the addition of two sculptures of lions, which flank the entrance, designed by Luxembourger Auguste Trémont. During the German occupation of the Second World War, the German occupiers converted the basement from market halls into offices, greatly increasing the amount of office space in the building. After the war, the building played host to the first meeting of the High Commission of the European Coal and Steel Community, chaired by Jean Monnet on 8 August 1952.
