Borgboda (also called Borgberget), located in Borge hill, Saltvik, is the largest hillfort in Åland with an area of total three hectares. When it was in use, around 1000 AD, the hill was surrounded by water on three sides. Steep hill was enforced with walls of stone and timber, remains of which can still be seen, along with remains of a few buildings. It is believed that Borgboda was never permanently inhabited, but functioned as a place where nearby people fled to when threatend.
The area near Borgboda s rich with prehistorical sites. There is a large iron age burial ground right before the hill, and sizable bronze age cairns are located just a few hundred meters north of the site.

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.
