The Sainte-Croix church of Oloron-Sainte-Marie was built from 1080, at the same time as the city of Sainte-Croix was established. Served by canons of the Augustinian order, the church was a parish until the 14th century. It was transformed for a time into a Protestant temple from 1569 to 1621.
Architecturally, the plan is made up of a nave and two side aisles ending in a choir extended by a cul-de-four apse. The north portal is from the Romanesque period, and is decorated with carved capitals. On the other hand, the side portal built in the 19th century was removed in the 20th century to restore the church to its original appearance.
One of the distinctive features of the church is its ribbed dome of Byzantine and Mozarabic inspiration which covers the crossing of the transept. Inside, barrel or semi-barrel vaults are also typical of Romanesque art, like the many capitals with plant motifs or evoking biblical themes.
In the 19th century, large frescoes representing the 'Passion of Christ' and the 'Last Judgment' were painted, particularly in the choir. There is also a pulpit and stalls from the beginning of the 18th century as well as the altar and its altarpiece in the Spanish Baroque style, dating from the same period (1708).
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
