Torre di Federico is an octagonal ancient tower that was allegedly a summer residence of Frederick II of Hohenstaufen. The two floors possess beautiful vaults. The aspect of the building is austere. It was part of a bigger complex, named Old castle and destroyed by Arabs. Remnants include some pieces of the old, imposing walls on the top of the green hill where the Tower rises.
The tower is an imposing 26 metres high, has a diameter of 17 metres and its walls are 3.5 metres thick.
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.
