The Roman temple of Château-Bas is a Roman ruin located to the east of Vernègues, in the park of the “Château-Bas” wine estate located along the road connecting Vernègues and Cazan. It dates from the late 1st century BC.
The temple, located in the center of a semicircular sacred enclosure, is today reduced to a few ruins. A large fluted column is surmounted by a capital with acanthus leaves. A smooth pilaster is located at the corner of the cella (closed part of the temple) and surmounted by a square capital with acanthus leaves.
A Romanesque chapel of modest dimensions (Saint-Cézaire chapel in Château-Bas) leans against the eastern wall of the Roman temple, partially reusing it.References:
The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
