Сан-Паоло-фуори-ле-Мура
Obtaining relatively little support from outside sources, John fell back on what resources he could command. He reinforced the walls previously restored by Pope Leo IV. As the Basilica of Saint Paul Outside the Walls was located outside the Aurelian Walls, and had been damaged in a Saracen raid, the pope fortified the basilica, the monastery, and the nearby dwellings of the peasants. He also founded a papal fleet.
