Jardin Japonais Pierre-Baudis

An archaeological museum with Roman artefacts from around Toulouse as well as the largest collection of Roman busts found in France. The site in ancient times was a necropolis then a hospital for pilgrims on the road to Santiago. The present building is from 1523 and became a museum in 1892.

A red-brick church from the 11–12th century, it may well be the largest Romanesque construction in the world, partly because it was an important stopover on the pilgrimage to Santiago. Huge as it is, it's the only remnant of the former Abbey of Saint-Sernin. Notable features are the great bell-tower, the gates, the "ambulatory" passage, and the thunderous organ. In the 19th century the church was "restored" by the famous French architect Viollet-le-Duc: some of his re-imaginings of the Middle Ages are now being undone. Saint Sernin or Saturnin (d 257) was one of a group sent from Rome to Christianise 3rd century Gaul; he was martyred by being dragged to death by a bull.

Deconsecrated mother-church of the Dominicans (called Jacobins in France because their first convent was in Rue St-Jacques in Paris). Built in Gothic red brick, it contains St Thomas Aquinas' relics. It's now a museum, enclosing the convent, refectory, chapel of St Antonin and Salle Capitulaire.

Magnificent red-brick building in Neoclassical style, lording it over the pedestrianised main plaza. It houses City Hall (with a grandiose "Salle des Illustres") and the city's main theatre. They no longer do guided tours but you can see much of it free.

Vast former abattoir now housing a contemporary arts museum, and there is also a nice garden overlooking the Garonne.

This church was founded in 410 AD as a pagan temple to Apollo but demolished in 1761. The present neoclassical building was completed in 1883 and restored in 2017–19.
