largest sundial in the world

indian guides seem quick to boast, but supposedly this sundial in jaipur is the largest sundial in the world. and who would want a larger one?


built a few hundred years ago, supposedly it can measure time to within 2 seconds. the sundial was in an outdoor observatory. at first, we thought we were entering some modern art sculpture garden, because all the tools had the useless look of modern art. but they actually are used to take observations and perform calculations! you'd think those things were modern art too, check it out:


in this next image, i'm walking down the sundial. my quads were throbbing after going up and coming down. it was tougher than any stairmaster! not that i know, but it was tough.
