Jantar Mantar

Lonely Planet review

The most eccentric of Delhi’s historic sites, Jantar Mantar (equivalent to ‘abracadabra’ in Hindi) looks like an enormous abstract sculpture, but this odd collection of curving geometric buildings has a purpose – the monuments are carefully calibrated to monitor the movement of the stars and planets. Maharaja Jai Singh II constructed the observatory in 1725 – it's an extremely popular place to pose for a portrait.
