The Saint Michel Basilica, near the tower of the same name, is one of the most beautiful in the city. Gothic style, was built in the 12th century. It had a land in front to accommodate the cemetery but in the 15th century this land was used to build the tower. It is a basilica, a major city church, in Gothic Flamboyanes style. It is shared with Saint André Church, the cathedral of Bordeaux. It is a landmark that is part of the district with the rest of the UNESCO world heritage.

The basilica has its bell tower (in this case, it is more than 110 meters high and dominates the medieval quarter) that is separated of the church building. The crypt is still visited, where there were mummies and was a very respected place.

It was built a larger church when the Saint Michel's one was included in the city walls.
