Amruth Sarovar (a stepwell)

At Tipu Sultan's summer hunting getaway, Nandi Hills, there's a stepwell.
While building a stepwell would have been the proper thing for an 18th century ruler to do, Tipu didn't build this one.  It was constructed in 1932--that makes it the youngest stepwell I know of.

The stepwell is spring fed and supplies water to the nearby plant nursery.

It's closed off to the public from walking into it...
...but I may have disregarded that 'suggestion' to get a closer look from the inside...
