The Mail & Custom’s House is rare and historically significant building in Eckerö. It was designed by famous Finnish architects C.L. Engel and C. Bassi and completed in 1828. The purpose of the building was to indicate the power of Russian Empire to seafarers coming from Sweden and it was built intentionally too large for the custom and post office need.
The Mail & Custom's House is well preserved. Today it functions as the post museum and there are temporary exhibitions.
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.
