Orivirran saarto is a ruin of the 16th century fortress. It was built probably in 1540's, because in 1546 Russians complained about Swedish cutting forest and gathering stones in Orivirta. There were probably a main castle, outer fortication, watchtower and dock. During 16th century it was garrisoned by 400-600 men and 5-10 cannons.
In 1592 Russian cossacks destroyed the fortress. In a fight over 200 men were died and Swedish lost a ship and several cannons. After defeat Orivirran saarto was changed to guard place and fortified again during the Russo-Swedish War in 1656–1658.
Nowadays there remains some ruins of the fort restored by the Finnish National Board of Antiquities. There's also a memorial erected in 1965.
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.
