Sidon Mithraeum
France
The Sidon Mithraeum was a Mithraeum in Sidon, Lebanon, discovered in the late 19th century by antiquarian Edmond Durighello and now lost. A number of statues and a marble bas-relief were found on site; these were part of the décor of a Mithraeum, an underground sanctuary dedicated to Mithras, an Iranian deity whose cult, reserved for initiates was especially popular among Roman soldiers. A brief note by the Durighello, who sold the sculptures to Louis De Clercq, offers a doubtful and fanciful description of the Mithreum. It is believed that the structure is located under the car park of the St. Nicholas Greek church in Sidon, but has not been excavated in modern times.
