This ancient underground church feels like stepping back in time. Built on the exact center of Roman Milan, it offers a quiet, atmospheric escape from the busy streets above. With its old floors, beautiful frescoes, and deep historical ties, it’s a perfect spot for anyone who loves Italian culture, hidden gems, and medieval history.

What is the Crypt of San Sepolcro?

The Crypt of San Sepolcro is actually a full underground church (not just a small crypt) beneath the Church of San Sepolcro. Construction began around 1030, funded by a wealthy Milanese mint master named Benedetto Rozzone. It was first dedicated to the Holy Trinity and consecrated in 1036.

In 1100, right after the First Crusade recaptured Jerusalem, the Archbishop of Milan changed its dedication to the Holy Sepulchre (San Sepolcro) to celebrate the Christian victory. The crypt sits directly on the site of the ancient Roman forum of Mediolanum, Milan’s old central square. Its floor still features original Roman stones from the 4th century. The space has five naves supported by slim columns, starry frescoes on the vaults, and interesting terracotta statues, including one of Saint Charles Borromeo praying. Leonardo da Vinci himself studied and drew the church and crypt during his time in Milan.

After being closed for about 50 years, it reopened to the public in 2016 following careful restoration.
