ATTOCK, a town and fort in British India, in the Punjab, 47m. by rail from Peshawar, and on the east bank of the Indus. The Indus is here crossed by the military and trade route through the Khyber Pass into Afghanistan. The river runs past Attock in a deep, rapid channel about 2ooyd. broad. The rocky gorges through which it flows, with a distant view of the Hindu Kush, form some of the finest scenery in the world. Since 1883 an iron girder bridge of five spans carries the North-Western railway to Peshawar, and has also a subway for wheeled traffic and foot passengers. The fort of Attock was built by the emperor Akbar in 1581, on a low hillock beside the river.
