Liège City Hall, Town hall in Liège, Belgium.

Liège City Hall, called La Violette, is a freestanding U-shaped block on Place du Marché, built from 1714 to 1718 in classical style with a slate hipped roof. Its stuccoed brick facades have a limestone plinth, corner blocks and window surrounds; the front gable bears the year 1718 and the coats of arms of the prince-bishop and the two burgomasters. A double ceremonial stair stands against the front, and the rear wings are closed by an 18th-century cast-iron gate.

A house called La Violette on the Place du Marché served as the city's meeting place from the 13th century, where burgomasters were elected. It was destroyed by Charles the Bold's troops in 1468, rebuilt in 1480, and ruined again by French bombardment under Marshal de Boufflers in June 1691. The first stone of the present building was laid on 14 August 1714 by architect D'Auberat, engineer Sarta and friar Colomban; work lasted four years.

The name La Violette comes from the sign of the 13th-century bourgeois house where the city magistrates met. The building later hosted the first two sessions of the unofficial Walloon parliament in 1919 and 1922, chaired by Jules Destrée, and on 24 July 1919 the French president Raymond Poincaré awarded the Legion of Honour there to Belgian soldiers who had delayed the Germans at Liège in 1914.

The building stands free on Place du Marché, near Place Saint-Lambert, with its double state staircase facing the square. The rear wings are closed by an 18th-century cast-iron gate. The interior, with its stucco, paintings and Louis XIV to XVI furniture, is seen on guided tours; check times before coming.

The building has held exceptional heritage status from Wallonia since 2002, not 2009. Its front pediment carries the year 1718 and the coats of arms of the prince-bishop and the two burgomasters of the year, a detail easily missed from the square below.
