Triparadeisos or Triparadisus (Greek: Τριπαράδεισος) was a settlement in Lebanon near the sources of the Orontes. A paradeisos was a hunting reserve or pleasure-ground for the nobility of the Achaemenid (Persian) Empire, normally a walled-in area with groves of trees, wild animals, and running water.
Triparadeisos was the place where the Treaty of Triparadisus occurred, in which Alexander the Great's Empire was divided between his generals in 321 BC. It has been suggested that it was at the site of Roman Heliopolis (modern Baalbek).[1] Heliopolis was a colony of the Roman Empire in what is now Lebanon. The name was Colonia Julia Augusta Felix Heliopolitana.
