The Church of San Sepolcro in Milan was originally founded in the 11th century. It has gone through several changes over the centuries since then, but the main attraction for most visitors is the crypt underneath the church.
Most of the renovations to the church were made in the 17th century. The crypt under San Sepolcro was reopened in 2016 after 50 years of being closed. There are 11th-century frescoes, Medieval graves, and Roman paving stones in the crypt. The 14the-century sarcophagus in the church is said to contain earth brought to Italy from Jerusalem by the crusaders, as well as a lock of Mary Magdalene’s hair.
The church is just behind the Pinacoteca Ambrosiana, and was a particular favorite of Leonardo da Vinci - so much so that when he drew his map of Milan, he put the Church of San Sepolcro at its center. Some of those drawings are on display in the Biblioteca Ambrosiana.
An audioguide is included with the price of admission to the crypt, so visitors can take a self-guided tour.
