The Church of Our Lady was initially dedicated to St. Michael. Its original form dates from the year 1439, and in the 17th century it was restored. Hence its exterior and interior are significantly baroque.
Next to the central altar from the 18th century, there is a painting of Mary with the Child. The church is richly decorated with four paintings representing the stages in the life of St. Augustine. They were initially attributed to F. Fontebasso, but today they are considered to be the work of G. Agnelli, a pupil and successor of the great Piazzeta. The wall intarsia and the wooden frame, made by the Venetian carver Brustolone, are also worth mentioning.References:
The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
