History & Architecture of Jantar Mantar

Commissioned in 1728 by Maharaja Sawai Jai Singh II, Jantar Mantar was part of a series of five observatories built across India — in Delhi, Ujjain, Varanasi, Mathura, and Jaipur. Of these, Jaipur’s is the most extensive and most accurate.
Jai Singh II, an avid scholar of mathematics and astronomy, aimed to refine the astronomical tables and improve the accuracy of calendars used in Hindu and Islamic traditions. The instruments, made of stone and marble, were designed for naked-eye observation and remain impressively precise even today.
In 2010, UNESCO recognised Jantar Mantar Jaipur as a World Heritage Site for its cultural and scientific significance, representing a fusion of Indian science, architectural excellence, and royal patronage.
