Leonardo da Vinci's Walled-Up Workshop Found

A laboratory once used by Leonardo da Vinci for his research into the natural sciences, but later sealed off by adjacent construction, has been found at a monastery next to the Basilica of the Santissima Annunziata, in Florence, Italy.

The laboratory contains numerous frescos bearing clear resemblance to Da Vinci's other works, and its use by Da Vinci was documented in letters written by Pietro di Novellara to Isabella D'Este in the 16th century CE. The suite of rooms was walled in during construction of a stable next door to the site.
