The ancient Pieniny castle was built on northern slope of a steep hill. The complex was small, due to lack of space, but placed in a spot which provided natural defence. The length of the defensive walls was 88 meters, and the walls were 1 meter thick, made from the local limestone rock. The gate was located in western part of the castle, below which cellars were built. According to Jan Długosz, during the disastrous Mongol invasion of Poland (1259), Prince Boleslaw V the Chaste fled to the Pieniny Castle (spelled as Castro Pyeniny), together with his mother and wife Kinga of Poland. Historians however doubt Długosz, claiming that construction of the castle was not initiated until the 1280s. The complex guarded southern border of Lesser Poland, and probably was abandoned by the first half of the 14th century, to be destroyed in the 15th century (most likely in 1433, during a Hussite raid.

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.
