What is the name of Michelangelo's final, unfinished sculpture?

Michelangelo’s final unfinished sculpture is the Rondanini Pietà.

The marble group shows the Virgin Mary supporting the emaciated body of the dead Christ, returning to the Pietà theme he had explored in his celebrated Vatican sculpture of 1499. Michelangelo began this late work around 1552 and continued revising it until the final days of his life in 1564.

Unlike the polished naturalism of his early Pietà, the Rondanini sculpture has elongated figures, rough surfaces, and an almost weightless, spiritual quality. Michelangelo repeatedly cut into the marble and changed the composition; remnants of an earlier conception, including a detached arm and legs, remain visible.

The work was unfinished when Michelangelo died, but its incomplete state is central to its meaning and appearance rather than merely evidence of failure. It is now displayed at the Museo della Pietà Rondanini in Milan’s Sforza Castle. The Palestrina and Florentine Pietàs are related works, but neither is his final sculpture.
