The Brazillian Olympic Swimming team spent a week staying at Jurys Inn Croydon before leaving for the Olympic Village.
Team Brazil stayed at the Wellesley Road hotel, between July 16 and 24.
The swimmers will be using the pool at Crystal Palace National Sports Centre as their training base during the Olympic Games.
On Sunday, the Paraiso School of Samba led a parade through Crystal Palace Park, at a Brazilian themed event to welcome the team.
The Big Dance Carnival kicked off with the procession before performances of a number of different dances including line dancing, flamenco and bollywood dancing.
Proceeds from the fundraising event were donated to Harris Hospice Care and St Christopher's charity.
