The original Husen castle, documented for the first time in 1246, was probably built here by the dukes of Zähringen in the 12th century. It given into the possession of the counts of Freiburg. In 1303, the castle went to the counts of Fürstenberg as a result of the marriage of Verena of Freiburg.
Count Henry IV of Fürstenberg had the castle extensively remodelled and expanded from 1453 to 1477. A neck ditch and an outer ward guarded the actual castle with its palas and bergfried.
The castle was the residence of the prince’s castellans (Burgvögte). In 1632 it burned down and was rebuilt. In 1643 French-Weimar troops under Jean Baptiste Budes de Guébriant destroyed the castle.
Later the ruins were incorporated into fortified earthworks or schanzen in order to defend the valley against enemy troops. In 1896 the bergfried was given battlements instead of the tower’s conical roof. In 1968 the town of Hausach purchased the ruins from the House of Fürstenberg. Today, parts of the palas wall, the so-called battery tower and the bergfried survive.

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.
