Saint-Mammès Cathedral of Langres

Highlight • Religious Site

Langres is a beautiful place that is probably of Celtic origin. About 2000 years ago the Romans surrounded the city with the fortress.
The city was destroyed by the Vandals around 407 and then rebuilt much smaller. In 731 the city was destroyed, this time by the Saracens.
In 1284, Langres, along with all of Champagne, became part of the French kingdom. In the 14th and 15th centuries, Langres was expanded into a powerful fortress.
It's easy to take a walk along the four-kilometer-long city wall with its twelve towers and seven gates. There is also a small tourist “train” that runs here.
Also worth seeing is the St-Mammès Cathedral, built in the Burgundian-Romanesque style with a touch of Gothic. They were built in two phases around 1160 and 1220.
We have made a stopover in Langres for the third time with our motorhome, up in the citadel with a wonderful view of the landscape, and we are happy to come back.

Langres, town hall

Highlight • Monument

In 1581, after more than two centuries of existence, the alderman acquired a vast Gothic residence on Place du Marché-aux-Blés (now Place de l'Hôtel-de-Ville). In addition to the municipal administration, the new town hall housed the court and, soon, the prisons of the royal justice. It was the fire in the latter that led to a complete reconstruction of the building from 1774. Under the direction of Nicolas Durand, architect of the generality of Champagne, the new town hall took over and arranged the municipal, judicial and penitentiary functions of the old town hall. Thus, the royal prisons were rebuilt behind the building. Treated as a projection, punctuated by an imposing colonnade and topped with a pediment, the central part constitutes the major accent of the façade. This escaped the fire which, in December 1892, ravaged the rest of the building. In the pediment, the acronym RF (French Republic) replaced the royal arms carved during the Revolution; however, it is the same angels who carry the republican shield!

Porte de l'Hotêl de ville

Highlight • Other

The Porte de l’Hotêl de ville or Porte Gallo-Romaine, in Langres is one of the seven gates around the fortified town of Langres, whose origins date back to Gallo-Roman times. The gate was built in 1592, was given a barbican in 1620 and was rebuilt in 1750. The gate gave direct access to the markets and was an important passage for trade. The gate has an impressive frieze with gargoyles and a coat of arms with the fleur-de-lys. The gate is a national monument and one of the 20 most beautiful sights around Langres. 😊

Porte des Terreaux

Highlight • Other

The Porte des Terreaux is a historic gate in Langres. It is one of the gateways to the fortified city, which is surrounded by a 3.5 km wall. The gate was built in the early 13th century to allow military convoys to bypass the city center. The gate had a double drawbridge and a barbican, a defense structure that was later demolished. The gate also has a mâchicoulis cornice (extension above the entrance), a medieval architectural element.

Tufière de Saint-Ciergues

Highlight • Waterfall

The tufa are sources that cause calcareous concretions, which give them an unusual appearance. These concretions are sometimes in the form of giant stairs, causing a succession of more or less high waterfalls.

Lake Mouche

Highlight • Lake

The Mouche reservoir lake: a quiet place dedicated to fishing. A forest track and a lakeside path go around it, before arriving at the dam bridge. A 'must' in the surroundings of Langres.
