The British team's preparation camp for the 2016 Olympics will be in Belo Horizonte, a 45-minute flight away from host city Rio de Janeiro.
The British Olympic Association has signed an agreement with the Minas Tenis Clube to host the preparation camp.
The facilities include several indoor sports halls and gymnasiums, a swimming pool used to host the 2008 FINA World Cup, and the 'Lagoa dos Ingleses' (Englishman's Lake) which has the potential to be used for rowing, canoeing and triathlon.
BOA chief executive Andy Hunt said: "Getting your pre-Games training and preparation environment right is absolutely essential to the success of an Olympic team on foreign soil.
"Today's announcement represents another major step forward in our operational planning and preparation for Team GB ahead of the Rio 2016 Olympics and a key part of our ambition to be the 'most local non-local team' at the 2016 Games."
