Así se preparó la Capilla Sixtina para el cónclave

Birds fly next to the dome of St Peter's basilica at the Vatican ahead of the cardinals conclave on March 9, 2013 at the Vatican. The Vatican installed a special chimney on the Sistine Chapel from which white smoke will signal the election of a new leader of the world's 1.2 billion Catholics as cardinals prepare for the centuries-old tradition starting on March 12.

This handout picture released by Osservatore Romano shows workers on scaffolding inside the Sistine Chapel at the Vatican on March 7, 2013. On March 5 the Sistine Chapel was closed to tourists to prepare it for the upcoming conclave. The next pope's ideal profile began to take shape as cardinals held a second day of pre-conclave talks — a man with pastoral experience, missionary energy and few ties to the Vatican's unruly government.

Photographers take pictures of the stoves which were setup in the Sistine chapel prior a cardinals conclave on March 9, 2013 at the Vatican. The two stoves with one common flue have been installed for the burning of the votes once they have been counted. Ballots will be burnt in one of the stoves, engraved with the names of the last six popes and the dates they were elected. Chemicals burnt in the second stove will ensure the colour of the smoke in the sky cannot be misread. AFP PHOTO / GABRIEL BOUYS
