Jantar Mantar: Meaning and History
Jantar Mantar is a group of five astronomical observatories built by Maharajah Sawai Jai Singh II between 1724 and 1730.
The name means 'instrument used for calculation' in Sanskrit.
These observatories were built to study celestial movements, measure time accurately, and track planetary positions.
The most famous ones are in Jaipur and Delhi.
However, modern buildings now block the view, making it impossible to use them for accurate observations today.
Each observatory is unique in size, materials, and construction, reflecting the innovative spirit of its creator.
