During 18 days, the city in the highlands of Puno, nestled on the shores of Lake Titicaca at an altitude of 3870 meters is the folkloric capital of the Americas. The festival brings together over 200 groups of musicians and dancers to celebrate the Candelaria Mamacha. The first nine days, the mayordomos (those in charge of organizing the festivities), decorate the church for Mass, banquets and fireworks. The main day (Feb. 2), the virgin is led through the city in a colorful procession comprising priests, altar boys and the faithful, Christians and pagans. This is when musicians and dancers enliven the city.
