The city of Islamabad, the capital of Pakistan, is located on the Pothohar Plateau within the Islamabad Capital Territory—one of the earliest known sites of human settlement in Asia. Some of the earliest Stone Age artifacts in the world have been found on the plateau, dating from 1 mln to 500,000 years ago. The crude stones recovered from the terraces of the Soan River testify to the endeavours of early man in the inter-glacial period. Items of pottery and utensils dating back to prehistory have been found in several areas.
