Harappa is an archaeological site in Punjab, northeast Pakistan, about 20 km (12 mi) west of Sahiwal. The site takes its name from a modern village located near the former course of the Ravi River, some 5 km (3 mi) southeast of the site. The site contains the ruins of a Bronze Age fortified city, which was part of the Cemetery H culture and the Indus Valley Civilization, centered in Sindh and the Punjab. The city is believed to have had as many as 23,500 residents—considered large for its time. In 2005 a controversial amusement park scheme at the site was abandoned when builders unearthed many archaeological artifacts during the early stages of construction work. A plea from the prominent Pakistani archaeologist Ahmed Hasan Dani to the Ministry of Culture resulted in a restoration of the site.
