The oldest parts of grey stone church date back to the 15th century. It was built in three periods: the first part probably in 1430s, second maybe in the later half of 15th century and latest in 1510s. The roof was destroyed by lightning in 1623 and the bell tower was built beside 1739-1740.
The Inkoo parish is very old (established in the beginning of 13th century) and it's quite probable there have been wooden churches before the present one.
Olargues is a good example of a French medieval town and rated as one of the most beautiful villages in France. It was occupied by the Romans, the Vandals and the Visigoths. At the end of the 11th century the Jaur valley came under the authority of the Château of the Viscount of Minerve. The following centuries saw a succession of wars and epidemics, and it was not until the 18th century that Olargues became re-established. This was due to the prosperity of local agriculture and artisanal industry.
The Pont du Diable, 'Devil's Bridge', is said to date back to 1202 and is reputed to be the scene of transactions between the people of Olargues and the devil. The old village is clustered around the belltower, which was formerly the main tower of the castle (Romanesque construction). The old shops have marble frontages and overhanging upper storeys. A museum of popular traditions and art is to be found in the stairs of the Commanderie.
