The Church of the Three Crosses (Vuoksenniska chruch), designed by academician Alvar Aalto, is architecturally an interesting building. Its slender, high belfry describes a down shot arrow. Instead of the altar painting there are three crosses. Among the 103 windows only two are identical. Aalto planned the church also for other activities in the parish besides services. Therefore the church can be divided into three parts. In the church there are seats for 800 persons. The windows and lightning are high up, which creates fascinating display of light and shadow. The Church of the Three Crosses was completed in 1957. The stained glass on the ceiling is as old as the church and also designed by Alvar Aalto.
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.
