What it is

Monumental well reached by flights of steps and galleries down to the water table, which varies greatly between the monsoon and the dry season. It served as a reservoir, a cool meeting place and a temple; Rani ki Vav (Patan, 1063) is its most elaborate example.

The chronology of the earliest rock-cut stepwells at Junagadh is uncertain (2nd-7th centuries); thousands were built up to the 19th century.

What it led to

  • water supply in the semi-arid regions of western India
  • religious and civic water architecture (baoli, vav)
