Bagacum (Today Bavay) was an Roman city and remarkable remains of ancient forum still exist. The 2,5 hectare are contains ruins of a central esplanade, temple and cryptoporticus (covered corridor or passageway).
The birth of Bavay after the conquest was the result of the reorganization of the territory by Augustus (probably between 16 BC and 13 BC). The town became the capital for the Nervii under the name of Bagacum and was an important junction of seven roads, the meeting-place of which was marked by a milestone, destroyed in the 17th century and replaced in the 19th century by a column.
From the Claudian period and especially under the Flavians in the late 1st century the city grew. Large monuments were built: a forum, thermal baths fed by an aqueduct bringing water from a fountain near Floursies located twenty kilometres away, and other buildings with a seemingly official nature adorned the city.
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.
