The Old Church of Loppi, also known as Santa Pirjo (St. Birgit), was built in 1660s. The history of simple and bare wooden church is quite unknown because documents of building were destroyed by fire. According some investigations the church could be completed already in the tide of 15th and 16th centuries, but the age of wall logs is dated to the year 1666.
Only couple of tombs remain of the old cemetery near the church. Nowadays Loppi Old Church is popular wedding and concert church.
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.
