Kong Humbles Grav ("King Humble's Grave") is one of Langelands most well-known prehistoric dolmens. It is about 55m long and 9m wide. Around the sides of the long barrow there are set of 74-77 kerb stones. The archaeological excavation has revealed c. 4000 years old human bones in the grave. The grave name is misleading, because the King "Humble" is believed to lived in c. 300-400 AD.

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.
