Birseck Castle is also called Vordere Burg Birseck and is one of four castles on a slope called Birseck that confines the plain of the Birs river. Burg Reichenstein sits on a higher slope to the north.
The origins of the castle probably date back to the age of Counts of Frohburg in the 12th century. Bishop Lüthold of Basel bought the castle hill from the Niedermünster monastery in 1239 and built the present castle in 1243/44.
In the 15th and 17th centuries Birseck was expanded. It served during the Counter-Reformation as a residence for Bishop Christoph Blarer (around 1600). In the middle of the 18th century, a stone bridge replaced the drawbridge.
In the 18th century, the castle was poorly maintained. In 1763 , Karl von Andlau moved his county seat from the castle down to the village. During the French Revolution in 1793, some parts of the English garden, the Ermitage and the building of the castle were set on fire or destroyed by drunken peasants. In 1808, Conrad von Andlau and Canon Heinrich von Ligerz acquired the ruins. The tower and the chapel were restored to their original state in the neo-Gothic style.

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.
