The site is known today as 'Klisi Tepe', named after the ruins of a Byzantine church, and archaeological excavations were started by the Swedish Institute at Athens in 1975.
To the north are the Rhodope Mountains, while to the south the river Nestos has created a large plain, that extends 30 km towards the Aegean Sea.
[3] The archaeologist Rainer Felsch first encountered the site in 1972 and noted surface finds indicating the presence of human activity from the Late Neolithic period to the Bronze Age.
Swedish archaeologists Erik J. Holmberg and Pontus Hellström travelled through the area of Paradeisos searching of potential excavation sites in 1975.
