Château de Laréole was built in 1579 by Pierre de Cheverry, a son of a great pastel merchant. The construction of the castle lasted three years and the Cheverry family kept the castle until 1707. After the Great Revolution, the castle changes hands several times before it was abandoned in1922. In 1984 the General Council of Haute-Garonne bought the property and restored it. Today the site is open to the public and guided tours are available.
Bomarsund fortress and garrison was built in 1832-1854 by Russian Empire to defence Åland Islands against enemies. British and French fleet attacked against it during the Crimean War in 1854. After a week of fighting the British stormed the remaining fort. Anglo-French forces destroyed it totally after battle. In the Treaty of Paris 1856, the entire Åland Islands were demilitarized, which is a status that has been preserved until this day.
Nowadays there are some ruins left and fortress area is open for visitors.
