Church of Santa Eulalia of the Monastery of Arnoso was originally founded in the 7th century on the initiative of San Frutuoso, Bishop of Dume and Braga. It was destroyed by the Moors in the 11th century. It was later rebuilt by King García II of Galicia.
It is a simple church in early Romanesque style with a nave, a barrel vault and a rectangular apse with blind arches. The wooden portal consist of round arches and a tympanum with a cross pattée. These round arches are profusely decorated with geometric, intertwined and zoomorphic elements.
Inside the church there are a few sixteenth century frescoes with episodes from the life of Our Lady. The two crosses on top of the roof show some similarities with Celtic crosses.
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.
