Stenberga was an ancient castle built probably in the 14th century. It was fist mentioned in 1389 and built probably by Jakob Abrahamsson, the bailiff of Turku. In 1438 the castle was donated as the site for Naantali Bridgettines Abbey, but in 1443 the abbey was decided to move to the Ailos. The castle was located to the rock hill near Masku River. There has probably been a 13 x 13m tower made of stone.

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.
