At the end of the 3rd century Arlon was fortified with the construction of ramparts. This castrum was 800 metres in circumference with walls that were 4 metres thick and 8 metres high with two gateways and around 20 watch towers. The Neptune tower was identical to the Jupiter tower recently discovered near to the Town Hall. The small museum consists of remains of the tower which were discovered during archaeological excavations in 1948. In the foundations of the wall one can see various sculpted stones from the ancient vicus including asuperb bas-relief representing Neptune. To visit the Neptune Roman Tower, a key can be obtained from Maison Knopes, 24 Grand Place.
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.
