Harappa is an archaeological site in Punjab, Pakistan, about 24 km (15 mi) west of Sahiwal.
- The site takes its name from a modern village near the Ravi River's former course which now runs 8 km (5.0 mi) to the north.
- The current village of Harappa is less than 1 km (0.62 mi) from the ancient site.

Fortified citadel and town planning were two common features in Harappan city because according to city planning, the city was divided into upper city and lower city.
- The citadel was built on a raised platform while the lower town was located on the lower part of the town.
- The lower town was larger than the citadel.
- Public buildings like the Great Bath were built in the citadel, the lower town usually had only residential buildings.
- Another feature that suggests the Citadel is of higher importance is that the fortifications around the area were bigger and stronger than those around the rest of the city.
- Common features of the Indus Valley Civilization are the development of irrigation systems, personal sanitation, town planning, the construction of burnt brick houses, foundries, the manufacture of metals, ceramics, cotton, and woolen textiles.
Hence, the correct answer is Harappa.
