Maringret’s Ruins – Bybassos


Bybassos/Erine was a fortified settlement of the Hellenistic period, the ruins of which lie across two hills (Hisar Tepe) adjacent to the ocean at Hisarönü village which lies approximately 20 km west of Marmaris on the Knidos peninsula. The ruins include  walls and fortifications from more than one time period. The ruins are rather sparse.

There seem to have been 2 locations for Bybassos – it was first placed east of Datça. However, ” Bybassos was long believed to be represented by the ruins at Emecik, on the Knidian peninsula 10 km E of Datça (Reşadiye), and the Bybassian Chersonese to be the E half of that peninsula, but this is demonstrably wrong.” (from Persus database entry on “Bybassos”) Furthermore, “Excavation after WW II revealed an inscription recording that the temple was dedicated to Hemithea, proving that Kastabos was at Pazarhk and that the fortified site at Hisarönü is Bybassos. (from the Perseus database entry on “Kastabos”) The initial site (east of Datça) is where the WikiMapia website still places it. The Vici website also lists “formerly known as Erine or Rina” which it attributes to G. E. Bean (1971).

There are sites of at least 2 eras at this location:

  • a neolithic settlement site of which very little remains
  • a Byzantine/Ottoman fortification on the hill top – which may be be on top of an earlier construction

site rating definitions are here.

There is very little left of the ancient site, the Byzantine/Ottoman fortification atop the western hill has survived much more. It is worth remembering that when ancient Bybassos was formed, the two hills that today are surrounded by fields of crops and houses were most likely either a rocky promontory standing out from the shore or actually a discrete island.
