Losing things at a festival like Boom is completely normal, especially with so much open space and so many hidden spots to relax and forget about material possessions. Items are found throughout the event, and even more turn up during the clean-up and breakdown. 

So, if you're looking for something, it's possible it's on the list of items we've made available on this link. 

This service is available until 30 October. 

If you have lost a passport, ID card, bank cards or wallets with ID, these items were delivered to the authorities (GNR) of Idanha-a-Nova.
