With a long history as a vantage point for anti-popes forces threatening Rome, Viterbo became a papal city in 1243. During the later thirteenth century, the ancient Italian city of Viterbo was the site of five papal elections and the residence of seven popes and their Curias, and it remains the location of four papal tombs. These popes resided in the Palazzo dei Papi di Viterbo alongside the Viterbo Cathedral intermittently for two decades, from 1257 to 1281; as a result, the papal palace in Viterbo, with that in Orvieto, are the most extensive thirteenth-century papal palaces to have survived.
