For thousands of Brazilian families, tomorrow's opening ceremony is happening in their backyard - or at least, what used to be their backyard.
They're the families who have been evicted from their homes to make way for car parks and hotels, and the sight of favelas at the entrance clearly wasn't what organisers had in mind.
The lights that shine from the buildings of Olympic Park cast a shadow over a community that lies right underneath.
Six-hundred families had legal rights to live here but were evicted by force; 14-year-old Naomy de Oliveira's family was one of them.
In her new home 20 minutes away, she's scared to leave the courtyard - she misses the safety of the one favela renowned for being free of drug-traffickers.
"It is very sad, I knew everyone in the community," she says.
"I could just scream and someone would come for help, but now I'm really far from all my friends."
Her family had no choice but to accept the government's offer of money or a new home after municipal guards trashed all their belongings while her family was at carnival.
"The government treated us like dogs," she says.
She's never seen what's gone up in place of her home so she came with Newshub to see it - it's now a luxury hotel.
The hotel is right at the main entrance for media at Olympic park and only 50 metres down the road is Vila Autodromo.
Twenty families actually refused to leave and the government was forced to build new nicer looking homes for them - on Wednesday (local time) Naomy came back to see those families for the first time. The reunion is bittersweet.
The families here have only just received keys a few days ago after pressure from aid workers.
"They wanted to make sure that they receive the keys before the Olympic games are over," says Andrea Florence from child relief agency Terres des Homes.
"[They wanted] to have the whole media here, and make sure they are handed over while media was watching."
