A delightfully-accessible 13th-century fortress that now lies in ruins above Bosanska Krupa, this should be your first stop when in town. There isn’t a huge amount to see within the ruins (they are ruins, after all), but that intangible sense of history that only decrepitude can create is most certainly here. The views are stunning too, extending over both side of the city with the rivers playing a starring role. The fortress was originally in Croatian hands, although it eventually fell to the Ottomans in the 16th century, at which point the town began to grow. The Ottomans were sure to keep this spot well-stocked, as it was an important stronghold for their ambitions to spread west, although it never really worked out for them in that respect. This is history, intangible history, with added beauty.

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.
