This basilica was built in honor of Mary, and the construction started in the 5th century. It has been rebuilt several times, but some of the original walls can still be seen in the church. According to the legend Mary showed where to build the church as she made snow fall on the location where they were to build the church. In memory of this they throw rose leafs on the visitors on the same day every year still, on August 5th.
The church, or basilica, is located on the Esquiline Hill in Rome and has free entrance. It is open from 9.00 till 19.00 every day.
