The Basilica of Saint Clement, dedicated to Pope Clement I, is especially notable for its three historical layers. The 12th-century basilica is built on top of a well-preserved 4th-century church (with many frescoes), which was built next to a 3rd-century Mithraic Temple. For an admission fee, it is possible to explore the excavations of the lower two levels, which is a fascinating journey into the history of Rome.
This ancient church was transformed over the centuries from a private home that was the site of clandestine Christian worship in the 1st century to a grand public basilica by the 6th century, reflecting the emerging Catholic Church's growing legitimacy and power.
The current basilica was rebuilt by Cardinal Anastasius, ca 1099-ca. 1120. Today, it is one of the most richly adorned churches in Rome. The ceremonial entrance (a side entrance is ordinarily used today) is through an atrium surrounded by arcades, which now serves as a cloister, with conventual buildings surrounding it. Fronting the atrium is the chaste facade of Carlo Stefano Fontana, supported on antique columns, and his little campanile (illustration). The basilica church behind it is in three naves divided by arcades on ancient marble or granite columns, with Cosmatesque inlaid paving. The 12th-century schola cantorum incorporates marble elements from the original basilica. Behind it, in the presbytery is a ciborium raised on four gray-violet columns over the shrine of Clement in the crypt below. The episcopal seat stands in the apse, which is covered with mosaics on the theme of the Triumph of the Cross that are a high point of Roman 12th century mosaics.
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.
