On the mound near L'Agout river, in Saint-Sulpice-la-Pointe, are preserved ruins of the keep and the chapel of the old castle built around 1240 by the Albigensian lord Sicard Alaman.
The castle is listed as a historic monument, it is one of the unmissable sites of the city of Saint-Sulpice-La-Pointe. Perched on the old castle mound, the remains of the Castela Castle chapel founded by the great Albigensian lord Sicard d'Alaman in 1240 testify to the rich historical past and the strategic position of Saint-Sulpice in the Middle Ages. The castle will be destroyed during the Wars of Religion in the 16th century by Protestants. Following the tragedy, notables Toulouse will decide to rebuild all the houses of the country house with the bricks of the castle. That's why today only a few remains of the old fortress. The site of Castela now offers a beautiful green setting to enjoy a family picnic.
References: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.
