This is an astronomical observation site in Jaipur, India, built by Maharaja Jai Singh II, in the early 18th century (1727-1734).

It includes a set of some twenty main fixed instruments, in most cases huge structures.

The Giant Sundial is the world's largest sundial, standing 27 meters tall and its shadow moves visibly at 1 mm per second.
