Santi Giovanni e Paolo al Celio is an ancient basilica in Rome, located on the Caelian Hill. The first church was built there in 398, and a series of ancient Roman rooms with frescos were discovered under the nave during 19th-century excavations. The altar, in the background of this photograph, is built over a bath containing the remains of John and Paul, two Roman soldiers martyred under Emperor Julian in 362, and to whom the basilica is dedicated.Photograph credit: Livioandronico2013
