Les Jacobins was built by St-Dominic to ensure the converted heretics didn't revert after the fall of Toulouse during the Albigensian Crusade.

Many hIstoric buildings, streets and squares in Toulouse centre ville are marked with interpretative signs explaining their significance. Half of the sign is in French; the other half is in Occitan, the traditional (pre-Albigensian Crusade/pre-conquest-by-French king) language of southern France. But the Occitan tells a very different story than the French.
For example, the sign for a leading from le jardin de plantes says (in French) that the street name is derived from the name of so-and-so, who lived in this building from this year to that year (a mere 1000 years ago). The Occitan section describes how so-and-so, for whom the street is named, was one of the Cathar defenders of Toulouse against the French and Catholic crusaders during the Albigensian Crusade.
