A restoration in the Italian most famous and historical monument Colosseum has yielded ancient traces of colorful frescoes as well as graffiti and drawings.
The restorers cleaning the Colosseum discovered the artworks in the internal passageway, between the second and third levels of the first Century Colosseum of the building.
The frescoes remains located under decades of calcified rock and grime of the 2,000-year old arena were uncovered in vivid red, blue, green and white colors.
The team also found ancient sketches of crowns and palm trees as symbols of victory painted by the spectators who celebrated success of gladiators they supported.
The remains were discovered in a wooden gallery reserved for the lowest classes which was furthest from the scene at the time.
The first floor belonged to the senators, while the emperor and Vestal Virgin priestesses had special boxes with the best views.
"This is a beautiful archaeological surprise," said Rome's archaeological superintendent Mariarosaria Barbera, adding that "even in a monument as well known as this one, studied all over the world, there are still new things to discover."
