The 12th century fortified church of Santa María de Ujué stands on the highest point of the town. It is a fine example of Romanesque architecture, with Gothic additions.
The church originates back to the 9th century when Iñigo Arista ordered a temple to be built next to the fortress that this king ordered to be built. This first pre-Romanesque church was demolished to erect a new Romanesque building in the 12th century under the auspices of King Sancho Ramírez. In the 14th century, Charles II ordered part of the Romanesque naves to be demolished in order to build a single Gothic building. The choir, the undertowers, the crenellated towers and the façades were also built, as well as the church was surrounded by promenades and walls. All of this gave the complex the appearance of a fortress that it still has today. Interred in the church is the heart of Charles II of Navarre.
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.
