Several tombs of antipopes were desecrated and destroyed, often by their rival claimants, shortly after their creation. For example, Pope Innocent II razed Santa Maria in Trastevere (one of the main Marian basilicas and one of the oldest churches of Rome) to the ground and was eventually buried over the spot once occupied by the tomb of his rival, Pope Anacletus II. Others survived centuries, only to be destroyed during conflicts such as the French Revolution and the War of the Spanish Succession, a fate common to some non-extant papal tombs. Such was the case with the tomb of Antipope Felix V (the last historical antipope), who was buried with most of his predecessors as Count of Savoy in Hautecombe Abbey.
