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.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
