This observatory in India has a history of 300 years and boasts a unique style that remains timeless even today

The Jantar Mantar observatory must be the first astronomical site I visited, and the first time I was so impressed by such architecture. I remember that for a long period since the 18th century, India was under British invasion, and this observatory was built in that very century. The then prince, Maharaja Jai Singh II, was an avid astronomy enthusiast. To unravel the mysteries of the sun, moon, and stars, he constructed this massive observatory next to the city's palace. Today, this observatory is listed as a World Heritage Site and is one of the must-visit attractions in Jaipur. The 300-year-old observatory features a minimalist design that is still fashionable today. The solid-colored geometric structures against the deep blue sky create a fascinating contrast, and from any angle, one can capture a stunning photo. However, this site attracts many visitors, so it's best to avoid the crowds. The observatory comprises 14 geometric instruments used for measuring time, predicting eclipses, tracking celestial bodies in orbit, measuring the angular tilt of planets, determining the altitudes of celestial objects, and other related data, all of which are highly professional. If you have the chance to visit, don't just sightsee and check it off your list. Rent an audio guide at the entrance; it will explain the different uses of each instrument. Beyond the beautiful scenery, the history and technology here are truly fascinating.
