The sanctuary of Amfiaraio is located in Attic region, northward from Athens, in a narrow and small valley close to the coast in front of the Euboea island. Amfiaraio was King of Argos, also therapeutist and oracle.
The rests of its sanctuary date mainly from the IVth BC. Most of the other vestiges as temple, theatre and monuments go back to the Roman times.
