The Kerimäki Church is the largest wooden church in the world. Designed by Anders Fredrik Granstedt and built between 1844 and 1847, the church has a length of 45 metres (148 ft), a width of 42 m (138 ft), a height of 37 m (121 ft) and a seating capacity of more than 3,000. Altogether there can be 5,000 people at a time in the church.
It has been rumoured that the size of the church was the result of a miscalculation when it was built (supposedly the architect was working in centimetres, which the builder took to be inches, which are 2.54 times larger). Further studies, however, have shown that the church was actually intended to be as big as it is, so it could easily accommodate a half of the area's population at the same time.
During wintertime, services are held in a smaller "winter church" (built in 1953), since the main building has no heating.
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.
