Chaumont, the Poster Town
• The old town of Chaumont : Private mansions from the 15th and 16th centuries and bourgeois houses from the 17th and 18th centuries often adorned with elaborate doors and corbelled turrets housing spiral staircases. Well worth visiting is the Art and History Museum and the Crib Museum.
• The Keep of the Counts of Champagne : Built on a natural spur, the Keep towers some 45 metres high over the Suize valley. This Keep, built in the 11th and 12th centuries, is the remains of the Comtes de Champagne chateau. Originally for defensive purposes and then a tower to symbolise the power of the Counts of Champagne, then a prison, today the Keep is an exhibition area and site for numerous cultural events.
• The Basilica of Saint-Jean : Established as a collegiate church in 1474 and Basilica in 1948, the Basilica was built and altered between the 13th and the 16th centuries. The building mainly comprises a 13th century nave with 14th century aisles and a transept, with a choir and ambulatory built between the 15th and 16th centuries. The basilica houses numerous works of art: a sepulchre in polychrome stone, a Jesse Tree and works by the sculptor Bouchardon.
• The Viaduct : The most important viaduct in dressed stone in Europe, the Chaumont viaduct spans the Suize valley. It is one of the most remarkable works of art from the 19th century, and is 600 metres long and 50 m high.
