The Trappist Abbey of Tre Fontani has three churches on the grounds. One church is the abbey church. Another church contains, in its crypt, the cell where Saint Paul was imprisoned prior to his beheading. And the third church, the Church of the Martyrdom of Saint Paul, is the site of Saint Paul's martyrdom where the miracle of the Tre Fontani (the "three fountains") occured. Tradition says that when Saint Paul was beheaded his head fell to the ground and "bounced" three times. At each spot where his head touched the ground, a "fountain" (really, a spring) came forth from the earth. Above are photos of the three altars in the Church of the Martyrdom of Saint Paul under which are the three "fountains" (springs). Also pictured above is the entrance of the Church of the Martyrdom of Saint Paul and a bas relief (inside the front entrance) of his beheading.
