The correct answer to this open question is the following.
Although you do not mention what president you are referring to and in which year, we are going to assume that you are referring to Bolivian President Evo Morales, who took the presidency on January 22, 2006.
If that is teh case, then, President Evo Morales had an informal inauguration and took the oath in an important ancestral and archeological place called Tiwanaku, next to a large and beautiful lake 12,500 feet above sea level.
Evol Morales was the first indigenous president in the history of Bolivia, and he and his followers celebrated this hiatus with an indigenous ceremony led by the Aymara Indian tribe.
