Real Monasterio de Santa Ana is the headquarters of the Order of St. Clare in Badajoz and lies in the heart of the old city. It was founded in 1518 by Ms. Leonor de Vega i Figueroa, under the blessing of Pope Leo X, and belonged to the jurisdiction of the Franciscan province of San Miguel. According to the tombstone in the grounds, Figueroa was abbess of the monastery for forty years until her death on April 17, 1558. She was buried in the grounds, until moved to the Cripta Real del Monasterio de El Escorial.
The monastery underwent a major transformation in the 18th century although the original structure partly remains. Outwardly, part of the building has buttresses and a tower with two bells. On the vault of the chancel stands a lookout tower with a lattice brick convent, topped with pinnacles. The church of the monastery has a single nave which was rebuilt in the late 17th century, and the presbytery is covered by a late Gothic rib vault dated to the first half of the 16th century. The church contains numerous altarpieces, imagery, paintings, and silverware.
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.
