Metz Citadel

The Metz Citadel was a fort built at Metz, northeast France in the second half of the 16th century.

Early phases


After the French defeated the Holy Roman Empire in the Siege of Metz in 1552, the city became a French protectorate as the 'Messine Republic' with a French garrison. To house it, an artillery-proof citadel was begun in 1556, only four years after the siege. Although the protectorate was still technically and legally part of the Empire, the city was now a 'de facto' French possession.

The citadel's construction was ordered by François de Scépeaux de Vieille-Ville, governor of the Three Bishoprics and involved the Italian military engineer Rocco Guerrini The city's population was forced to take part in the works and supply the French troops' needs. Completed around 1564, the citadel reinforced the south-west sector of the city's medieval ramparts, which had proved the hardest area to crack during the siege but could no longer be adapted to advances in artillery. Its aim was to control the city itself and its approaches, with cannon that could be turned to fire in either direction. As with the Spandau Citadel, built on the same model, it had four angled bastions surrounded by a four-sided moat - the neighbouring lac aux Cygnes was the former canal, allowing a link between the moat and the Moselle. The supply depot is the last visible trace of the building of this era.

Some religious and secular buildings had to be demolished to build the citadel, but some churches were kept by the military authorities, such as the Templar Chapel and Saint-Pierre-aux-Nonnains. In 1648 the city was signed over to France in the Treaties of Westphalia and so the citadel was later integrated into a system of fortifications designed by Sébastien Le Prestre de Vauban from 1676 and brought to fruition by his pupil Louis de Cormontaigne between 1728 and 1749.

Present day
The citadel has recently been converted for civilian use - the former arsenal is now an auditorium, the supply depot a deluxe hotel. The porte Serpenois next to it is now only decorative and the former ditches have given way to green spaces such as the Esplanade de Metzand the jardin Boufflers. The Esplanade's gardens below place de la République were extended after the citadel's destruction and occupy the site of the former ditches dug in 1816.

The Governor's Palace was built by the Germans at the start of the 20th century on the site of a bastion of the dismantled citadel. Several Roman monuments and ramparts were brought to light on the site as well as the medieval Tour d'Enfer tower in the subsoil of the gardens.
