The Holy Cross Minster (Heilig-Kreuz-Münster) is the main Catholic church in Schwäbisch Gmünd. It stands on the site of a former, much smaller romanesque church. It took about 500 years to be completed, though not consecutively. Initial construction began around 1325 under the leadership of an unknown master builder on what was left of the previous romanesque church, the towers of which were still standing. In 1497, the south tower fell onto the north tower, which knocked over the north tower after a bow connecting the two was removed and in 1515, all repair work was finished.

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.
