A public interest petition was filed in the Madras High Court in October 2012 against the erection of the two-leaves insignia, but was dismissed by the court.
Entrance
Until 2012, the facade of the memorial was a tall entry arch with folded hands which was replaced with a concrete replica of two-leaves emblem, the symbol of the AIADMK party founded by M. G. Ramachandran. The facade was also given a Grecian touch with the erection of a 12-foot-high bronze sculpture of Pegasus, the winged horse of Greek mythology. The 3.75-tonne sculpture, by architect R. Ravindran, a sthapathi from Mamallapuram, is set on a 4.5-metre-high pedestal. Two 15.9-metre-high columns serving as the entrance were built with reinforced concrete. The elevated "two-leaves" structure is supported by a 6-metre-high beam serving as the stem. The leaf structure, with a span of 10.2 metres for each leaf, is a metre higher than the towering columns. The leaves have a slight resemblance to a honey comb and are visible from both the front and the rear.
Museum
A museum on M. G. R. is located within the memorial at the northern side of the campus.
