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.

This is the town's main square, built around the church. Needless to say you can find a boulangerie here and a coffee.

A former abbey, this church is fascinating with its unusual rampart-like fortifications. Inside, it is indeed a church.

Impressive 13th century castle. An association has been working on its rehabilitation since the 2000s. A medieval festival takes place in the village every year.

Small village surrounded by the beautiful surrounding countryside and beautiful small roads without traffic. Here you can take your coffee break!
