Going down the stairs, the light will turn on "miraculously".
This Romanesque Baptistery of pink brick is octagonal whose sections are separated by columns.
Whilst they were building the cathedral, the baptistery was used as the base for the bell tower in 1346.
Since the 1969 restorations, the baptistery has regained its original function with the installation of the baptismal lead font dating from the middle of the XIII century, decorated with two superposed friezes, one representing a procession of monks in quatrefoil, the other, rarer, exotic hunting with wild animals and imaginary animals from an oriental influence.
Since 1969 the baptistery welcomes five display windows precious church silver from the XIX century from Lombez Cathedral and other churches of the parish. In one of those display windows was a reliquary of Saint Majan's arm, patron saint of the village and the Saves, which was stolen in 2002.
Romanesque windows have been fitted with contemporary stained glass windows from a student of the famous glass artist Henri Guerin, native of Plaisance du Touch.
The door, which is lower, gives access to the organs and the bells during guided tours.
The floor of the baptistery is the original ground of the entire cathedral, that is to say 1.5 m lower than today. A look at the base of the first pillar in the nave makes it possible to see the base on the old floor.
Come out of the baptistery, make a few steps into the nave to have an overview and make the most of a chronological discovery of the riches of this cathedral.
