The Indian National Trust for Art and Cultural Heritage (INTACH) has awarded The Oberoi Grand, Kolkata, a blue cultural plaque for its heritage and historical significance as the "Grande Dame of Chowringhee." The hotel, which dates back to the 1800s, was transformed into a boarding house by Mrs. Annie Monk of Ireland and later into The Grand Hotel, Kolkata, in 1914. Under the leadership of Rai Bahadur Mohan Singh Oberoi, the hotel underwent a transformation, incorporating modern amenities like hydraulic lifts.
