Church of the Holy Sepulchre dates back to the fifth century, built by the bishop Petronius as a simulacrum of the Constantinian Sepulcher of Jerusalem and rebuilt at the beginning of the eleventh century by Benedictine monks after it was heavily damaged during the devastating 10th century Hungarian invasions.
In the church there is also a water source which, in the symbolism of the Stefan complex based on the passion of Christ, is identified with the waters of the Jordan, and which from the archaeological point of view refers to the sacred source of the pre-existing isiac complex. Probably the temple of Isis was in this area, as it seems demonstrated, as well as by the presence of the source (the cult of the Egyptian goddess required the presence of a source of spring water)
