The Russian Old-Believers (starovery) have kept their religious rituals unchanged for more than 1000 years. Today, there are 11 starover congregations with approximately 15 000 members in Estonia. A museum situated in Kolkja village on the coast of Lake Peipsi displays traditional clothes, crafts, tools, household items, and religious items of the Old-Believers.

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.
