On the altar is kept the alleged skull of St Valentine. On his feast day, February 14th, it is brought out and crowned with roses. It has to be admitted that this is a dubious relic. The original shrine of the saint was in his basilica near the Via Salaria (the remnants of his underground shrine could be seen until a recent landslide), but this skull was exhumed in the catacombs of St Hippolytus near San Lorenzo fuori le Mura in 1836. At best, it is of another Valentine.
