Peshawar is the capital of the Pakistani province of Khyber Pakhtunkhwa.Situated in the broad Valley of Peshawar near the eastern end of the historic Khyber Pass, close to the border with Afghanistan, Peshawar’s recorded history dates back to at least 539 BCE, making it the oldest city in Pakistan and one of the oldest cities in the world. Peshawar was the capital of the ancient Kushan Empire, and was home to what may have been the tallest building in the ancient world, the Kanishka stupa.
