In 2013, following Pope Benedict XVI’s resignation, the Sistine Chapel closed on March 5—five days after his resignation on February 28—and reopened on March 18, 18 days later. Pope Francis was elected on March 13, 2013. As this was a resignation rather than a death, there was no funeral.
In 2005, Pope John Paul II passed away on April 2. The Sistine Chapel closed the next day, April 3, and reopened on April 19, following the election of Pope Benedict XVI. The conclave was held April 18–19, beginning 16 days after John Paul II's death. In that case, the Sistine Chapel remained closed for 17 days.
Assuming a similar timeline for Pope Francis, who passed away on April 21, 2025, the Sistine Chapel would likely close on April 22 and reopen around May 8, depending on how quickly the conclave concludes and a new pope is elected.
The papal conclave is typically held 15–20 days after a pope’s death, allowing time for mourning and for all eligible cardinals to arrive in Rome. For Pope Francis, the conclave is expected to begin between May 6 and May 11, 2025. Recent conclaves have been relatively brief, so it’s likely that the Sistine Chapel will reopen by around May 14.
During this period, the Vatican Museums, St. Peter’s Basilica, and other Vatican sites generally remain open to the public—though visitors should anticipate larger crowds and heightened security.
