Further Information about the Jantar Mantar

The India name Jantar Mantar is derived from the two words yantra (instrument) and mandir (temple) which gives the enigmatic name of temple of instruments. During the British rule of India the name was mistranslated and became Jantar Mantra on all official documentation and this name has stuck ever since.
