Simorre is located in the Astarac region, a very hilly area in the south of Gers, with clay soil, which runs along the Lannemezan plateau. You will be dazzled by this small medieval village and especially by the Notre-Dame-de-l'Assomption church which sits majestically in the middle of the village. As it is fortified, it looks as much like a church as a fortified castle. It is surprising.
