The moment we entered, we were completely amazed by the massive stone instruments and how the increase it's geometry looked, it’s quite hard to believe that these structures were built centuries ago with such precision and accuracy that was reviewed recently. Our teachers explained how each instrument, especially the huge sundial, could measure time and track celestial movements so accurately. Although they couldn't really explain to such a vast amount of students verbally so they had us sit in a separate room and watch the slide show presentation of it all. It blew our minds to think that ancient astronomers could achieve all this without any modern technology. As we walked around, my friends and I couldn’t stop taking pictures. We kept guessing what each structure was used for before the guide told us the real answer which made it even more fun. The whole place had this fascinating energy, like stepping back in time and exploring a scientific wonder from another era. The site itself was very well maintained, with clear signs even on a side mandir which told us to remove footwears if had any 😊.Beyond the science, the architecture was equally captivating, it truly felt like an open air museum. After exploring, we grabbed some snacks at a nearby cafe and chatted about how brilliant Maharaja Jai Singh and ancient Indians must have been.
