The Basilica-Sanctuary of Maria Santissima Annunziata (also called 'Madonna of Trapani') was originally built by the Carmelite Order in 1315–1332 and rebuilt in 1760.
The church houses the skull of Saint Albert of Trapani in a silver statue crafted in the 18th century, and the relics of Clement of Ancyra.
It houses a marble statue of the Madonna of Trapani (Our Lady with Child), which might be the work of Nino Pisano. The statue is life-size, weighs 12 tons and is 165 cm high. To her left she is holding the baby Jesus.
The ancient convent today is the 'regional museum Agostino Pepoli', one of the most important Sicilian museum.
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.
