Arch of Constantine is a massive arch located between the two most important attractions of Rome - the Colosseum and the Palatine Hill. Considered to be the largest Roman arch ever built, it is dedicated to Constantine, a great Roman emperor.
The monument is known for its massive size that is 21 metres tall and 26 metres wide. It was built to celebrate the triumph of Constantine I over Maxentius at the Battle of Milvian Bridge in 312 AD. It consists of three arches in total - one big arch in the middle and two smaller ones on either side of the bigger one. The structure is made from big blocks of marble whose quality has been appreciated for its durability through centuries. Several sculptures have been made on the walls of the building along with the written texts that glorify the great Constantine I. The location of this monument makes it one of the most visited and photographed in the city.
