Crowne Plaza Chennai Adyar Park was built by Adyar Gate Hotels Limited (AGHL), a hotel company which owns four hotels in India, the other three being 105 room Intercontinental Resort Mahabalipuram, 104-room Welcome Hotel Grand Bay in Vizag and 67-room Fortune Hotel Sullivan Court in Ooty. Incorporated in 1970 (as a private limited entity), the company was originally promoted by T. T. Vasu (one of the promoters of T. T. Krishnamachari group, also known as the TTK group) and K. R. Veerappan. In 1975, the company became a public limited company. There were no operations in the company until 1979, when a group of NRIs took controlling interest in AGHL and started construction of the hotel in Chennai in 1981, which is the flagship property of the company. The hotel commenced operation with a tie-up with Holiday Inn.
