The Longos Vales's Monastery foundation is attributed to D. Afonso Henriques in the second half of the 12th century.
The only enduring element of the primitive medieval construction with its clearly Romanesque style is the main chapel, the remainder of the group was subjected to remodelling work when it passed into the hands of the Society of Jesus.
Nowadays, the monastery is private property, with the exception of the church which continues to be part of the parochial headquarters of the parish.
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.
