The church of Sastamala in Karkku (dedicated to St. Mary) was built in the end of 15th century. In the Middle Ages Karkku was the spiritual and administrative center for the northern Satakunta area. Unfortunately church was nearly abandoned for decades in the 19th and 20th centuries. During this time for example the floor was destroyed. The church was renovated in 1960-1977 and today it's used mainly for summer ceremonies.
There is a fine collection of historical artefacts in Sastamala church. Oldest items are probably a stone font from the 13th century and the part of gravestone with engraving "1304".
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.
