As you can tell from the previous few posts, our tour of Delhi, Jaipur and Agra included a lot of visits to tombs, forts and palaces. Throw in a couple of mosques and museums, and you’ve pretty much summed up the trip.
Except, that is, for the Jantar Mantars.
A Jantar Mantar is a uniquely Indian artifact: a set of giant, building-sized instruments for taking precise astronomical measurements. They were built in the 1720s and ’30s by Maharaja Jai Singh II of Jaipur in several cities, including ones in Jaipur and Delhi, which still exist.
