Chakdara has been an important center for the last 3,500 years and is littered with remains of the Gandhara grave culture, Buddhist sites, and Hindu Shahi forts.[citation needed] Buddhist sculpture of the first to seventh centuries from nearby sites and Hindu Shahi artefacts are now displayed at Chakdara Museum.The "Andandheri" or Andaan Dheri is a Buddhist archaeological site in Pakistan, about 4 miles north of Chakdara, excavated by Professor Ahmad Hasan Dani in 1966, for the purpose of establishing a chronology of Gandharan art and architecture.[1] Andaan Dheri, an important Buddhist site, is located 7 km north of Chakdara Bridge opposite to Gul Abad Degree College for Boys near the village of Uchh.According to another tradition, Gandhara is also thought to be the location of the mystical Lake Dhanakosha, birthplace of Padmasambhava, founder of Tibetan Buddhism.Three kilometres (1.9 mi) from Andannd Dherai Stupa, there is the Hindu Shahi fort of Kamal Khan Chena (spring, Urdu: چشمہ), which is now in ruins.
