Marseillan
Formerly in the hands of the Counts of Pardiac - who resided at the Château de Monlezun - the lands of Marseillan bordered on the County of Astarac.
In 1056, the local lord, Guillaume-Garsie de Troncens, donated the church to the Abbey of Simorre.
There was a local noble family, the de Marseillan, whose presence is attested to in the 13th century.
The Château de Marseillan, which stood to the south-west, has now disappeared, but was still under attack from Bernard de Faudoas in the 15th century.
In 1718, the local seigneury passed to the de Seissan de Marignan family, who had already established themselves at the neighbouring château de Marignan.
In the past - and even in the early Middle Ages - the settlement was partly grouped around the church, which was rebuilt in the 19th century. Although the church has a bell tower and porch, its semi-circular chevet pre-dates this period.
The south chapel features a keystone carved with the coat of arms of the de Seissan de Marignan family, in recognition of their generosity during the reconstruction.
