The Taj Mahal, built by Shah Jahan for his wife Mumtaz Mahal, stands as one of the world's most recognized monuments to grief and devotion — not a palace or a display of power, but a tomb built purely out of loss. The four minarets around it lean slightly outward by design, so that in the event of an earthquake they'd fall away from the tomb rather than onto it. Tip: security is strict — no food, tripods, or power banks past the gate. The monument is closed every Friday; check this against your travel date before booking a Friday group departure.
