Santa Maria dei Miracoli, also known as the 'marble church', it is one of the best examples of the early Venetian Renaissance including colored marble, a false colonnade on the exterior walls (pilasters), and a semicircular pediment.
Built between 1481 and 1489 by Pietro Lombardo to house a miraculous icon of the Virgin Mary. The plans for the church were expanded in 1484 to include the construction of a new convent for nuns of St. Clare to the east. The convent was connected to the gallery of the church by an enclosed walkway that was later destroyed.
The interior is enclosed by a wide barrel vault, with a single nave. The nave is dominated by an ornamental marble stair rising between two pulpits, with statues by Tullio Lombardo, Alessandro Vittoria and Nicolò di Pietro. The vaulted ceiling is divided into fifty coffers decorated with paintings of prophets, a work by Girolamo Pennacchi's contemporaries, Vincenzo dalle Destre and Lattanzio da Rimini.
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.
