The Pieta (1499)
In the right aisle, the first major sight is Michelangelo's beautiful PietÃ¡, located immediately to the right of the entrance in its own chapel. The sculpture depicts the Virgin Mary cradling the dead Jesus in her lap after the crucifixion. It was completed in 1499, when Michelangelo was just 24. After it was vandalized with an axe in 1972, the sculpture was placed behind protective glass.
