The five Jantar Mantars are located in Jaipur, Delhi, Ujjain, Varanasi, and Mathura. Among these, the Jantar Mantar in Jaipur is the most famous and holds the distinction of being a UNESCO World Heritage Site. Each Jantar Mantar features a collection of architectural astronomical instruments designed to measure time, predict eclipses, track stars, and determine celestial altitudes. The instruments are large, fixed structures made of stone and masonry, reflecting advanced scientific knowledge of the era. The Jantar Mantar in Jaipur, built between 1727 and 1734, is particularly notable for its massive instruments, including the Samrat Yantra, which is the world's largest stone sundial.

Jantar Mantar refers to a collection of astronomical instruments built by Maharaja Sawai Jai Singh II. These observatories were designed to measure time, predict eclipses, track the location of major stars, and determine the declination of planets. The instruments are large, fixed structures made of stone and masonry, showcasing ancient Indian astronomical and architectural prowess.
A UNESCO World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). These sites are designated for having cultural, historical, scientific, or other forms of significance, and are considered to be of outstanding universal value to humanity.
Maharaja Sawai Jai Singh II (1688-1743) was the ruler of the Kingdom of Amber, later Jaipur. He was a keen astronomer and city planner, known for founding the city of Jaipur and commissioning the construction of the five Jantar Mantars across northern India. His contributions significantly advanced astronomical studies in India.
UPSC and SSC often ask about UNESCO World Heritage Sites in India, their locations, and the historical figures associated with them. Be prepared for questions on the specific purpose of Jantar Mantar instruments.
