Under the Aosta old parish church, archaeological diggings brought to light the early Christian cruciform basilica, indicated as Concilium Sanctorum, the Assembly of Saints because it was built on the tombs of some of the early martyrs who were buried in the Roman cemetery area which in itself was built on a protohistoric funeral settlement.
Inside you can see parts of the liturgical structures, the relic platform with the tombs of three bishops who lived between the 5th and 6th centuries (Grato, Agnello, Gallo) and other tomb chambers dating from between the 5th and 8th centuries.
References:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
