The oldest part of the Sjonhem church is the tower, which was built in the 13th century. Originally it was attached to a much smaller Romanesque church. The choir and nave was however torn down and replaced with the current structure during the middle of the 13th century.
Inside, church frescos decorate the vaults; these also date from the 13th century. Also probably original are some stained glass windows. A crucifix on the altar is somewhat later, dating from the 14th century. The baptismal font is however considerably older, dating from the 12th century and thus older than the church itself. It was made by the stonemason known as Hegvald. The church has been largely unaltered since the Middle Ages; the greatest change occurred in 1818 when the sacristy was built.
References: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.
