Castelnuovo Magra is mainly known for its ancient castle which was once the capital of the Bishop of Luni's domain. The castle had been originally built in the 12th century by Bishop Walter and then later completed by Henry of Fucecchio who developed the Code Pelavicino. Quite a lot of changes and additions have been made to the castle over the centuries. Today, visitors can see the remains of the large ancient walls, the masonry sections of the original castle and the large tower which had a rectangular plan.
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.
