San Bernardino alle Ossa is a church in Milan, best known for its ossuary, a small side chapel decorated with numerous human skulls and bones. In 1210, when an adjacent cemetery ran out of space, a room was built to hold bones. A church was attached in 1269. Renovated in 1679, it was destroyed by a fire in 1712. A new bigger church was then attached to the older one and dedicated to Saint Bernardino of Siena. The church's origins date to 1145, when a hospital and a cemetery were built in front of the basilica of Santo Stefano Maggiore. In 1210 a chamber was built to house bones from the cemetery, next to which a church was built in 1269.
