Delhi's outdoor astronomical observatory is the earliest of five observatories built by Sawai Jai Singh II across India. It is dominated by a huge sundial and houses other innovative instruments that help plot the course of heavenly bodies.
The Delhi monument, red in colour, comprises of 13 architectural astronomy instruments that could be used to predict the timings and movements of the sun, moon and planets by charting astronomical tables.
Jantar Mantar's striking combinations of geometric forms have caught the attention of architects, artists and art historians from around the world.
On a visit to the Jantar Mantar in Delhi, the top four instruments that should not be missed are:
- the Ram yantra, used to observe celestial objects
- the Samrat yantra, an enormous sundial
- the Jai Prakash yantra, two elaborate hemispherical sundials
- the Misra yantra, which is a composite of five instruments
