When you enter this church you immediately know what sets it apart—its wooden hulled ceiling and unique details scattered throughout the church, from those who are buried within the floors and walls to the frescoes and Bishop's speaking altar.
However, what is hidden beneath this entry layer reveals the history of Christianity and demonstrates that it wasn't always a welcomed ideology.
Walk through the far right hand doors by the altar and head through the cloisters then down stairs where you'll be able to explore the first two foundations and buildings which this church is built upon. The first foundations are from the 11th century and the second is from the 13th. These are set lower almost at an underground level with no windows demonstrating the hidden nature in which the institution first had to practice within. The old fading frescoes show depictions of Jesus and his life and are a minimalist approach compared to the decor upon the first floor from the 14th century.
The Saints Fermo and Rustico is not only an architectural wonder for it's ceiling but an archeological expose revealing the history and evolution of Christian religion.
