The entrance to this single-street bastide is through an ancient, fortified gate reminiscent of a Tuscan campanile, with its machicolation and wooden hoarding which houses the bells of the church of St. Martin, just a few metres away. A little further on in the village is the 12th century Saint-Blaise chapel, just next to the Château d’Aon, a 13th century fortified house with an imposing, austere appearance, now converted into accommodation, with catering and entertainment. It overlooks the Grand Etang, on the banks of which there is a 14th century mill, a fishery and the Nasses bridge, built in the 15th century in freestone, in the purest Romanesque style. There are three walking trails, starting from the village square, to discover the surrounding area.
