Visit for the unusual meeting of science and architecture. Maharaja Jai Singh II built the Delhi observatory as part of a wider effort to improve astronomical calculations. The scale of the Samrat Yantra and the contrasting geometric forms are far easier to understand in person than from a diagram.
What to look for
The large triangular form of the Samrat Yantra
Red and white masonry instruments with distinct geometric shapes
Useful to know
Walk around the instruments to compare their forms rather than viewing the site from a single point.
Allow daylight for seeing the shadows and structure clearly.
