In the neighborhood of the fort of Rainau-Buch, the remains of several other Roman buildings are visible. For instance, there is the ruin of a monumental gate in the limes wall near the modern village of Rainau-Dalkingen, about a kilometer north of the fort. Originally, it was a wooden construction, but it was rebuilt several times.
In the final phase, at the beginning of the third century, it must have had a façade like the stage of a theater, with rather plumb columns. In the upper part of the gate, there must have been a bronze statue of an emperor, perhaps Caracalla, who defeated the Germanic tribe of the Alamans in 213, and may have started his campaign from Dalkingen. Twenty years later, the Alamans stroke back, and the gate was burned down.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. 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.
