Settled on a hill between the Lizet and the Baïse valleys, Estipouy was first a possession of the seigneurs de l’Isle-d’Arbéchan (l’Isle-de-Noé).
From the XIIth century, the ownership of the village has passed into the hands of the seigneurs de Montesquiou for eight hundred years, until the French Revolution.
According to some documents and remains (a circular feudal mould surrounded by ditches) the castle which doesn’t exist anymore could have been situated on the top of the hill ( north west of the village).
In natural surroundings, the recent church, restored during the XIXth century reveals a gothic style porch and an octogonal spire. This Church could have replaced a former monument : as a proof inside, the antique baptismal font dedicated to Saint Lizier, whose deeds in the Ariege department were recorded in the VIIIth century.
