Bionnus or Bionnos (Ancient Greek: Βίωννος) was a town and polis (city-state)[1] 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.[1][2]
The site of Bionnus is located near modern Pyrgos ('high ground'), about 2 kilometres (1.2 mi) south of Kerames.[3][4][1]
