The Felsenkirche, a church built into a natural niche in the rocks, rises high above the houses of Oberstein. Wyrich IV of Daun-Oberstein had it constructed in the years 1482-1484. Behind it, a wall of rocks rises steeply upwards; and under it, the houses of Oberstein nestle into the slope. On account of its prominent location, the church has become a symbol of the city. It can be entered only through a tunnel which was dug into the rocks.
The church’s greatest treasure is the medieval winged altar. It was created around 1400 by an unknown painter, the “Master of the Mainz Mocking”.
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.
