Legend has it that in the midsummer of the 4th century A.D., the Virgin Mary Tomon gave Pope Libero a monastery to show the glory of the Virgin Mary where it snowed. As a result, snow fell on Mount Esquilino the next morning, and the Pope ordered people to build a church there, so the church was also known as the Notre Dame Snow Palace. Today, the church also has activities to sprinkle white rose petals to symbolize the Holy site. It is also the first church named after the Virgin Mary in the world. The current Pope visits the Virgin Mary Hall before and after his visit to China. The church was built in about the fourth century A.D. The dome depicts the coronation of the Virgin Mary. The oil painting depicts the scene of the birth of the Virgin Mary.
