An important castle of north Greece on top of a hill in a very beautiful landscape. Although it is a big castle and very close to a road with heavy traffic, it is not easily visible. Moreover, it is not open to the public.

Excavations carried out on the hill and its environs have revealed traces of human presence since Neolithic times; on the basis of their construction and associated finds, the building walls and abutments unearthed in the southwest section of the castle date to the Hellenistic period. Rentina lies close to the settlement of Arethousa, which went into decline from the 6th century onwards. According to one interpretation, Rentina may take its name from the nearby staging post (mutatio) called Peridipidis (genitive: Peripidinis).
