So-called Jätinkirkko (“the giant’s church”) of Kastelli is a rectangular stone rampart measuring 36 x 62 meters. It dates back to the Stone Age and is one of the most significant ancient structures in Finland. The fort was probably built between 2700-2200 B.C like most of the stone constructions in northern Botnia.
The structure is located at top of the hill. The rampart, which is two meters high in its present state, has six gateways. In the environs are more than twenty rock cairns, a representative group of ten trapping holes and a stone age dwelling site lower on the slope.
Kastelli represents the earliest monumental construction in Finland in a form which is rarely found in hunter-catherer cultures. National Board of Antiques has submitted Kastelli site to the UNESCO Tentative List of World Heritage Sites.
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.
