Discuss the salient features of the Harappan architecture.
In short
Harappan architecture was planned, civic and utilitarian, built around a citadel and gridded lower town, standard bricks, covered drains and water storage rather than palaces or temples. Mohenjo-daro's Great Bath and Dholavira's three-part plan and reservoirs are its most striking examples.

Planned hierarchy
A raised citadel and a larger lower town at Mohenjo-daro and Kalibangan, and a three-part plan at Dholavira, point to an authority that organised labour and space.
Standard bricks
Baked and mud bricks in a uniform 1:2:4 ratio across sites hundreds of kilometres apart suggest shared building codes rather than local improvisation.
Drainage and water
Covered drains with inspection holes, hundreds of wells at Mohenjo-daro and Dholavira's rock-cut reservoirs show advanced civic engineering.
Great Bath
Mohenjo-daro's tank, about 12 by 7 metres, was made watertight with gypsum mortar and bitumen for ritual bathing.
Storage and assembly
Large platforms often called granaries and a pillared hall at Mohenjo-daro served collective needs.
Courtyard houses
Inward-facing homes of one or two storeys opened onto side lanes rather than main streets, with private bathrooms and often wells.
Restraint and variety
No palaces or temples survive, only fire altars at Kalibangan and Lothal, and builders used stone at Dholavira and mud brick at Kalibangan.
