"Historical Context
Governor of the Three Bishoprics, Marshal Charles Louis Auguste Fouquet de Belle-Isle, a supporter of the Enlightenment, decided to rethink Metz's urban planning in 1728.
After providing the city with a new theater on the Île du Petit-Saulcy—now the oldest operating theater in France—he wanted to open up the cathedral district by creating, as was common at the time, a central "royal square," surrounded by several public buildings.
With the site then occupied by churches, convents, and the Palais des Treize, which served as the town hall, negotiations began with the bishopric and the Metz bourgeoisie.
They would last twenty years, during which France would be embroiled in the Wars of the Polish and Austrian Successions. Metz, defending the state, would welcome King Louis XV within its walls and protect Stanislas Leszczynski, the king's father-in-law, whom he had placed in charge of the neighboring Duchies of Lorraine and Bar.
The Marshal-Governor finally called upon the architect Jacques-François Blondel for the Town Hall project.
Construction and Development
Construction of the new building began in 1761 and lasted ten years. An additional section, on the site of the Saint-Gorgon church, was not completed until 1788.
Built of Jaumont stone, the building, in a sober French neoclassical style, has a two-story, 92-meter-long façade overlooking the Place d'Armes, facing the left side of Saint-Étienne Cathedral.
Its façade comprises nine arcades surrounded by two avant-corps whose pediments were decorated by J.-C. Rollier and whose sculptures reveal the allegory of war, flags, lances, and shields, as well as the allegory of the city in the Salon de Guise, representing commerce, architecture, and the hand of justice.
Inside the building, past the peristyle, is a monumental staircase leading to the grand reception room, whose railing is by Joseph Cabossel and Pierre Janin. The door and window frames are by Claude Louvart and Louis Laforet.
Among the interior decorations, noteworthy are the two statues representing Justice and Prudence, which adorn the monumental staircase, as well as stained-glass windows by Laurent-Charles Maréchal.
A portrait of Lasalle, Napoleon's "mad" light cavalry general with numerous feats of arms, born in Metz in 1775 and killed at the Battle of Wagram in 1809 at the age of 34, is placed in one of the salons."
