Question

In the Hunger Games, there have been 75 different arenas. After the tributes are done killing each other, what happens to them? And after the revolution, do they get destroyed?

Answer 1

It's stated that the arenas were preserved by Panem;

Everything is brand-new, I will be the first and only tribute to use this Launch Room. The arenas are historic sites, preserved after the Games. Popular destinations for Capitol residents to visit, to vacation. Go for a month, rewatch the Games, tour the catacombs, visit the sites where the deaths took place. You can even take part in reenactments.

They say the food is excellent.

But destroyed after the Revolution

The questions are just beginning. The arenas have been completely destroyed, the memorials built, there are no more Hunger Games. But they teach about them at school, and the girl knows we played a role in them. The boy will know in a few years. How can I tell them about that world without frightening them to death?
