The Basilica of the Virgin Mary is the largest of the churches named after the Virgin Mary in Rome and the first church in the world named after the Virgin Mary. Located in Rome, Esquilino is one of the four Catholic Churches of the Holy See, the main square of the Basilica of the Virgin Mary, which has a marble column on the main square of the Basilica of the Virgin Mary, and the Constantine Assembly Hall from the ancient Roman market, on which the statue of the Virgin was added in 1615. A 75-meter-high bell tower was built for the church in the mid-13th century and rebuilt in the 14th century after being destroyed by an earthquake, and five bells in the bell tower ring every 9 p.m. to prompt prayer. From here, enters the Basilica of the Virgin Mary in Esquilino Square, the back door of the Basilica. Figure 1 Main Gate, Figure 5 Back Gate
