Monastery of Santa María de Aciveiro is a gem of Romanesque architecture, built in 1135 under the patronage of Galician King Alfonso VII and incorporated into the Cistercian Order around 1170. It was carefully restored with full respect to the original structure. Following the Cistercian layout, all rooms are organised around a cloister combining impeccable history, warmth and functionality: kitchen, refectory, scriptorium, chapter house, stables and monks’ cells.It was one of the first seven monasteries of the thirty-eight that belonged to the Diocese of Compostela. It is now a historic hotel, declared a Historic-Artistic Monument in 1931 and considered a Site of Cultural Interest.
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.
