St. Olof's Church was originally built around the year 1100 and it consisted of a main tower, chancel and nave. It was later extended, but the construction was probably interrupted when archbishop’s seat was moved to Gamla Uppsala in the 12th century.
St. Olof's church has been influenced by the Nidaros Cathedral in Norway, while the small tapering windows have an Anglo-Saxon style. The church is dedicated to the Norwegian viking Olaf Tryggvasson, king between 995-1000.
It is not certain by whom the church was built. Most probably it was authored by the Benedictines or local trade guild. Archaelogical excavations have revealed remains under the church, which are thought to have belonged to an even older stone church. It may have been one of the first built in Sweden.

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.
