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.

Ideal site for a family mountain bike outing without difficulties in a pleasant and quiet site. With a little luck you too will come across a litter of young wild ducks, a doe leaping on the canal or nutria in the middle of a nap! The old Roman road connecting Toulouse to Tarbes also borders the canal, in particular at the ancient crossing of several roads marked by the old oak of the Hurmagne which for the first time in many centuries has not produced any leaves this spring 2020. ..
