Eauze former cathedral is a national monument. It was the ecclesiastical seat of the former Diocese of Eauze, which was merged into the Bishopric of Auch, probably in the 9th century. Eauze Cathedral is dedicated to Saint Luperculus, who is said to have been a bishop here in the 3rd century before being martyred.
Odon, Count of Fezensac, founded a Benedictine monastery on this site After 960 AD. In 1088, the monastery was united with the abbey of Cluny and become then a priory. This status remained until the French Revolution. There exact time of construction of churches prior to the current church is unknown.
The construction of the present church was ordered by Jean Marre, who had became a prior of Eauze in 1463. The church had to be built on the site of a previous church, probably with three naves, which would explain the narrow width of the nave compared to its height (21.5 m at highest). The monument underwent a major restoration between 1860 and 1878.
References: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.
