The Benedictine Sorde Abbey in the village Sorde-l’Abbaye was founded at the end of the 10th century on the banks of the Gave d’Oloron river. This remarkable architectural ensemble overlooks a natural setting that is now protected.
The abbot’s residence from the 14th and 15th centuries was built on the remains of a Roman villa (3rd- 6th centuries). Currently being restored, the building is open to the public during the National Archaeology Days and European Heritage Days: tour of the thermal baths and ancient mosaics.
The monastery buildings were rebuilt at the end of the 17th century. They are open to the public from March to November.The abbey church's the tympanum, decorative capitals, Romanesque period mosaics and an impressive 18th century marble high altar are some of the most interesting works. A miniature model shows what the abbey looked like before it was last destroyed.
Sorde Abbey is listed as an Historic Monument and has been included in UNESCO’s World Heritage List as part of the Pilgrim’s Route in France to Santiago de Compostela.
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.
