Ramakrishna Mandir Kolkata (Calcutta)

The centrepiece of the Ramakrishna Mission complex at Belur Math is the huge 1938 Ramakrishna Mandir, which somehow manages to look like a cathedral, Indian palace and Istanbul's Aya Sofya all at the same time. That's deliberate and perfectly in keeping with the message of 19th-century Indian sage Ramakrishna Paramahamsa, who preached the unity of all religions.
