Reduce your carbon footprint

As a major source of CO2 emissions, the transport of festival-goers remains a priority issue in the age of ecological transition.

The Main Square Festival is already very committed in this area, and has signed a partnership with TGV INOUI to transport you to the heart of Arras by train, the mode of transport that emits the least greenhouse gases.
