Bjelaj castle, locally known as Stari Grad Bjelaj (Bjelaj old town), is a medieval town-fortress complex near the village of Bjelaj, Bosanski Petrovac.
Located on the edge of the Petrovac plain (or part thereof Bjelajsko fields), on the northern slope of the Osječenica mountain. The area around the city is uninhabited and lean. The whole complex is situated on a plateau about 850 metres long.
On the south end of the northern half, there is a great fort, a prehistoric site from the Bronze and Iron Age. On the north end, there is a small fort. The fort itself has two parts: a medieval southern and northern Ottoman part. The medieval town has a ground plan of an irregular rectangle over 40 meters long and a width of about 35 meters. From the tower on the west side is the beginning of the remains of a large pen that was added along with the medieval city in the Ottoman period.
First mentioned in written sources in 1495 and named after the whiteness (or tint) by which it stood out above Bjelajsko field. Between 1530 and 1537, Bjelaj came under Ottoman rule.
Bjelaj has two parts: the southern medieval and northern Ottoman part. The medieval city has a layout of irregular rectangles over 40 m long (north-south) and about 35 m wide (east-west). The entrance to the city is in the northward.

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.
