Taxila

Ancient city, northwestern Pakistan. Its ruins, including temples and a fortress, lie just northwest of Rawalpindi. It was the capital of the Buddhist kingdom of Gandhara and a centre of learning. Founded by Bharata, the younger brother of Rama, it came under Persian rule and in 326 BC was surrendered to Alexander the Great. Ruled by a succession of conquerors, including Bactrians and Scythians, the city became an important Buddhist centre under King Ashoka (c. 261 BC). The apostle Thomas reputedly visited it in the 1st century AD. Taxila's prosperity in ancient times resulted from its position at the junction of three great trade routes. When they declined, the city sank into insignificance; it was finally destroyed by the Huns in the 5th century. Taxila was designated a UNESCO World Heritage site in 1980.
