Imagine a giant astronomical calculator built with stones and shadows. This is called Ram Yantra - made up of two big, cylindrical structures with open tops. Using the sun's position and shadows, people could figure out the time of day, the position of stars, and even the length of the year. And it's built hundreds of years ago!!
