This video was shot on my phone at the site where Battalia Royale 3 was performed. The sound quality isn't great but you can see the spaces and buildings where the work was performed. 

Imagine upwards of 30 performers running around, performing bloody fight scenes, audience crammed in wherever they can.

The whole place is tumble-down buildings and old concrete stairs. Up one end there is a swimming pool that was empty during the performances. This was site specific theatre on a big scale!
