After numerous studies and investigations, the project to provide the Colosseum with a new arena, which ideally took shape in 2014, enters the operational phase. This ambitious program aims to recover the original image of the iconic monument by restoring its nature as a complex scenic machine and strengthening its protection and conservation with particular attention to the protection of underground structures.
The new arena in Accoya, a resistant and durable technological wood, is part of a purposive sustainable choice that avoids the killing of valuable species allowing high performance, almost no maintenance, resistance to any bacterial aggression, and deterioration resulting from environmental agents. Some portions of the floor involve the construction of mobile panels, which, thanks to rotation and translation, guarantee flexibility, making it possible to naturally illuminate the underground structures.
Set at the same Flavia level as the pre-existing wooden floor, the new mobile flooring is entirely walkable, can be opened in various configurations that can be managed remotely and monitored together with environmental data. The opening and closing cycles, which can be activated several times a day, allow the correct conservation of the underground structures. They create a functional and interactive continuum for a visit experience without interruptions and with the archaeological constructions perfectly visible.
The activation of the mechanisms during the visit to the hypogea is created to produce new and exciting views. The natural light amplifies the majesty of the Colosseum, restoring the essential reading of the monument and allows the public to fully understand the use and function of this icon of the ancient world, also through cultural events of the highest level.
The project also provides for the positioning of 24 mechanical ventilation units distributed along the perimeter to control the temperature and humidity of the underground rooms; in just 30 minutes, the complete exchange of the entire volume of air is guaranteed.
Finally, to feed the public baths of the monument, the construction of a rainwater collection and recovery system is ready to welcome the approximately 20,000 people who visit the Flavian Amphitheater every day.
