Bionnus

Bionnus or Bionnos (Βίωννος) was a town and polis (city-state) of ancient Crete. It is known by epigraphic evidence. In a list of theorodokoi of Delphi from 230–210 BCE, Bionnus is mentioned between Psycheion and Matala.

The site of Bionnus is located near modern Pyrgos ('high ground'), about 2 km south of Kerames.
