Islamabad Capital Territory, located on the Pothohar Plateau of the northern Punjab region, is considered one of the earliest sites of human settlement in Asia. Some of the earliest Stone Age artefacts in the world have been found on the plateau, dating from 100,000 to 500,000 years ago. Rudimentary 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.
