Did Pope Julius II die before the completion of the Sistine Chapel?

Yes, Pope Julius II died on February 21, 1513, before the Sistine Chapel was fully completed. While he commissioned the chapel and the famous ceiling frescoes painted by Michelangelo, the ceiling was not finished until 1512, shortly before his death. The chapel itself was consecrated in 1483, but the extensive artistic work continued well after Julius II's passing.
