Musée Dupuy Mestreau

The large cathedral that's the namesake of the district dominates the old town. There has been at least two cathedrals here earlier, a Merovingian cathedral founded by St Pallais, and a Romanesque cathedral of which the southern cross and a dome have been incorporated in the current building. The Gothic cathedral was once much higher, up to three times higher than its current version. Traces of the ridge raising up to 39 m are still visible on the bell tower, and arcs on the outside raise up above the roof. During the 15th and 16th centuries it was built to those grand proportions, and the cathedral was almost finished when it was largely destroyed by Protestant troops in 1568 during the French Wars of Religion. There weren't funds to rebuild it as large as it had been, and the current height is about a third of what it once was. Surrounding buildings related to the cathedral like the bishops' residence were also not rebuilt.

One of the last parts of a 17th-century citadel. A few decades after its completion, the region of Saintogne revolted against the king, the rebellion was struck down, and Cardinal Richelieu ordered the citadel to be torn down. In addition to the governors house, there's little left of the fortifications. Later a Carmelite convent, a hospital (later wrecked) and a chapel was built on the grounds. The older buildings have been incorporated in the new Saint-Louis residential district.

A Dominican monastery established in 1292, it was rebuilt in the 15th century. After the revolution it became a dwelling house. In the 19th century a certain Maurice Martineau with a large collection of books lived there and as he passed away in 1928, the house and the books became the property of the city. Therethrough the municipal library came into being, and which it has been ever since. Only the Gothic choir with its grand bay and inscriptions reveal that this was once a house of worship.

An art museum in a former échevinage (a seat of municipal institutions under the Ancien Régime), classed as a historical monument. The artworks on display are mostly from the 19th century by French painters.

The most "medieval" street of the old town, at least when it comes to the houses lining it which were untouched by the 17th century building project. As there are relatively few businesses, it's much less busy than the shopping streets and even overlooked by visitors spending a short time in the city.

Formerly known as Parc Bassompierre, the garden on the Charente river offers great views to the old town and the cathedral. It's divided into a French and an English garden, and has a music kiosk and a playground for children.
