The first castle at Burgistein was built by Jordan I of Thun (later of Burgistein) in 1260. Jordan III of Burgistein fought on the losing side in the Battle of Laupen in 1339. In retaliation a Bernese army attacked and destroyed the castle in 1340. It was rebuilt in the following years.
In 1397 the Burgistein family died out and the castle was inherited by Werner Münzer. Over the following century it passed through numerous owners until 1484 when the Wattenwyl family acquired it. They owned the castle until 1714, when it passed to the Graffenried family. The 14th-century castle was rebuilt in the 15th and 16th centuries.

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.
