The Gateway of India, Mumbai
Concierge.com's insider take:
Nothing reinforces your sense of having arrived in the city quite as emphatically as the Gateway of India, Mumbai's defining landmark (at the end of C. Shivaji Maharaj Marg, near the Taj Mahal Hotel). Designed by George Wittet (who also designed the Prince of Wales Museum), the 85-foot yellow basalt gate was intended to commemorate the 1911 visit of King George V and Queen Mary. Unfortunately, it was not finished until 1924. In 1947, the last British troops departing from India marched away through the arch.
