Two prominent Harappan archaeological sites are:
1. Mohenjo-Daro: Situated in modern-day Sindh, Pakistan, Mohenjo-Daro stands as one of the best-preserved urban centers of the Harappan Civilization. Its features include a meticulously planned grid of streets, an advanced drainage network, and exemplary urban design. Excavated in the 1920s, the site remains vital for comprehending Harappan culture.
2. Harappa: Located in Pakistan's Punjab region, Harappa is another key Harappan Civilization site. As one of the earliest discovered cities, it offers critical evidence for the evolution of Harappan urban society. Harappa is especially significant for its organized street layouts, granaries, and sophisticated agricultural techniques.
