Answer 1

Most possibly the oldest steel plant in the world

The earliest evidence of steel making in the ancient world, dating back to 300 BC, has been found in the Samanalwewa reservoir area. In comparison, England's first steel making occurred in 1491. The early furnaces were ingeniously powered by natural draught-the monsoon winds-rather than the forced draught (bellow-operated) method employed elsewhere. Recent excavations found the ruins of a steel plant (built circa 300 BC) manned solely by wind power. Sri Lanka did indeed export high quality steel to Persia to make the famed Persian swords.
