The construction of the Chiesa di Santa Maria Annunziata (dedicated to the Annunciation of the Virgin Mary) was begun in 1453 by the architect Filippo delle Vacche of Caravaggio. It is built in the Late Gothic style to replace the previous edifice that stood at the site. Its façade remains unfinished.
The church preserves within it paintings by Romanino, Moretto da Brescia, Zenone Veronese and Paolo Veneziano. There is a grand polyptych of gilded wood dating from 1510. There are frescoes executed by Antonio Vassilacchi dating from 1602.
The main entrance into the church is through the great portal executed between 1506 and 1508 by Gasparo Cairano and Antonio Mangiacavalli, who were among the chief exponents of Renaissance sculpture in Brescia.
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.
