About Santa Maria degli Angeli e dei Martiri
The Basilica of Santa Maria degli Angeli e dei Martiri (St. Mary of the Angels and the Martyrs) is a large and impressive 16th century church constructed within the remains of the Baths of Diocletian and masterminded by renowned renaissance artist Michelangelo.
Though centuries had passed since the fall of the Roman Empire, the massive Baths of Diocletian were still standing in the 16th century. Taking advantage of the huge structural shell, the new Christian basilica was built inside the great hall and frigidarium. It was to be the last great work of Michelangelo, who began the project in 1563 but died in 1564, before its completion by Jacopo Lo Duca, a pupil of Michelangelo’s.
One notable feature of Santa Maria degli Angeli e dei Martiri is the meridian line built into its floor and gaps in the ceiling used to measure the passage of the stars.
The sheer scale of the build is not only impressive in its own right, but also gives a good indication of the size of the original baths, of which this is only one part. Those looking to find a more unaltered view of the original baths should visit the nearby Aula Ottagona.
