Built in 1835 by a raja from the prosperous Mallick family, this resplendent mansion is as grand as it is curious. Arguably one of India's best-preserved royal homes, its marble-draped halls are overstuffed with dusty statues of thinkers and dancing girls, much Victoriana, ample Belgian glassware, game trophies of moose heads and fine paintings, including supposedly original works by Murillo, Joshua Reynolds and Rubens. Admission is free, but you need prior written permission from West Bengal Tourism.
Of particular note within the building is the music room, lavishly floored with marble inlay, where Napoleons beat Wellingtons three to one. The ballroom retains its vast array of candle chandeliers with globes of silvered glass to spread illumination (original 19th-century disco balls!). There's also a private menagerie on the mansion's grounds, dating back to the early years, which is home to a few monkey and bird species.
To find Marble Palace from MG Rd metro, walk north and turn left at the first traffic light – 171 Chittaranjan (CR) Ave. From the east, it's on the lane that leaves Rabindra Sarani between Nos 198 and 200.
