A colourful and vibrant Opening Ceremony took place as the11th South American Games were declared open in the renovated Félix Capriles Stadium in Cochabamba.
Bolivian President Evo Morales was among those present for a ceremony also attended by officials including Panam Sports chief, Neven Ilic.

"Together, we and Bolivia have shown that surrendering is not an option, that there is no insurmountable obstacle," said South American Sports Confederation President Camilo Pérez.
"We have overcome them all and that is why we are full of joy, and from now on it is up to you, my beloved athletes, that with your effort, fair play and brotherhood, give a message to our continent, the transforming message of the Olympic world, a message to build a better world through sport."
The ceremony took place in a packed stadium and was highlighted by the arrival of the South American flame after a month long tour of the country.
