By the time I got to Jantar Mantar, I was burned out on tour guides, so I did not get one. It would have been nice to have one, because it is a series of astrological and astronomical instruments that I did not quite understand on my own.
Nonetheless, it was a beautiful place. Basically, the structures are scientific equipment used to measure time, days, etc. Construction began in 1727 by a Mughal emperor. They are calendars and clocks (and so much more), but they are also beautiful as works of art. It was a photographer’s paradise.
Note the coming rain storm — I was about to get wet!
See Hawa Mahal in the background?
