Tarrha was probably established in the Classical period and was a very important religious centre; it was one of the earliest sites of worship of Apollo.
Tarrha is frequently cited in the ancient sources such as Pausanias,[4] Stephanus of Byzantium,[5] and the Stadiasmus Maris Magni.
According to Greek mythology, Apollo, after murdering Python, went to Tarrha to be cleansed through purgatorial rituals ministered by the temple priest, Carmanor.
The coins belong to the 3rd and 2nd centuries BCE, when Tarrha became a member of the Republic of Cretans.
Robert Pashley was the first modern archaeologist to find the location of the city and investigate it.
The area held scattered stone stele which are inscribed with a double axe symbol.
