Fort de la Conchée is an island fortification constructed by Sebastien Vauban. In 1689 Vauban conducted an inspections of French coastal fortifications for King Louis XIV, who wished to strengthen and improve the country's defences. In 1693 whilst the fort was being constructed the English raided the town. They landed on Conchée where they slighted the works and captured those working on the fort.
Again in 1695 the English, with their Dutch allies, attacked the fortress. Though the fort was unfinished, ten guns had been installed, which permitted the French to repulse the attack. The battery then turned its guns on the main attacking fleet causing much damage to it. The fort was finally finished in 1705. The fortress was demilitarised in 1901.
During the Second World war the Germans used the abandoned fort for target practice. The Allies then attacked the fort during St Malo's liberation.
The fort covers almost the entire island. The fortress consists of a granite two-storey structure, with an upper terrace for the fort's armament.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
