A church at the site of current San Francesco, dedicated to St John, was present since perhaps the seventh-century, since nearby Christian burial appear to date from then. In around 1244, the church began to be administered by priests from the Cathedral of Acqui. Around 1410, it became associated with the Franciscan order, and rebuilt and rededicated. The convent was suppressed in 1802, and the church was affiliated with the Confraternity of San Giuseppe, who briefly changed the name of the church. In 1824, the Franciscans returned, and they rebuilt the church in a neoclassic-style, adding the Facade, under the design of Ferraris in 1835, completed in 1854.
Parts of the church are ancient. The bell-tower and apse date to the 15th century. But other parts reflect refurbishments along the centuries, including the 19th-century reconstruction. The broad brick facade (1835–1854) shows eclectic styles with a triangular lower tympanum and monumental order pilasters.
The interior houses an Immaculate Conception by il Moncalvo; an Adoration of the Magi by Raffael Angelo Soleri; and a Madonna and Child with Saint Francis and Antony of Padua by Pietro Beccaria. The ceilings were frescoed by the 19th-century painter Pietro Ivaldi, detto il Muto di Toleto.
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.
