The Leper’s Tower was built on the ruins of an ancient Roman tower and was originally known as the Friour Tower, after the family that lived there. This family, whose name was mentioned for the first time in 1191, also occupied the Ports Decumana, now abandoned.
After several changes of ownership, it was bought by the Order of Saint-Maurice in 1773 and was incorporated into a hospice of charity founded by Jean-Boniface Festaz. The current name derives from the fact that a leper named Pierre Bernard Guasco, a native of Oneglia was imprisoned there from 1773 to 1803. This story inspired Lepers of the city of Aosta, a story written by Xavier de Maistre, published in 1811.
In 1890, the tower was restored. Today it belongs to the Autonomous Region of Aosta Valley, which holds exhibitions at the site.
The Leper’s Tower was founded on a Roman tower whose foundations were excavated in the nineteenth century. A medieval tower was built on the site in the 15th century.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.
