The origins of ancient Anuradhapura revolve around the planting of the “tree of enlightenment,” Buddha’s fig tree brought to the site in the third century B.C. by Buddhist nuns. The ruins of Anuradhapura are evidence of the Ceylonese political and religious capital that lasted for 1,300 years until it was abandoned after an invasion in A.D. 993.

The city created a library that apparently rivaled that of the legendary library of Alexandria. Parchment was said to have been developed there. Pergamum became a sophisticated city, and its population swelled to 200,000. Among the ancient Roman and Greek ruins are a 10,000-seat amphitheater, places of worship, and a racetrack.
