The Ganesha Ratha is a fully completed rock-cut structure, while nearby rathas are incomplete. The current stone ratha is a replica of a wooden version which preceded it. Its construction is credited to Narasimhavarman I who reigned 630-688AD. While it is conjectured that this ratha was built prior to the other rathas of the area, there is no historical evidence to confirm it. The temple was originally dedicated to Lord Shiva but in the 1880s, villagers replaced the Shiva Linga with an image of Ganesha, after formally seeking permission from the District Collector, and may have been attributed to George V of England. The original Shiva Linga is installed under a tree nearby. Along with several other monuments, this temple gained UNESCO World Heritage Site distinction in 1984 as "Group of Monuments at Mahabalipuram".

The ratha is three tiered and studded with images and other architectural features which are found in other South Indian temples. The facade is a columned verandah flanked by sculptures of dwarapalakas. The columns are mounted on seated lions which are the typecast design of Pallava architecture. There are also two pilasters, which are also lion mounted, and they face each other. It is a rock cut structure. The cornices above the pillars have Kudu depictions along its entire length and these kudus are also depicted at the gable ends of the roof. Below the gabled roofs, on both long ends windows are carved in horseshoe shape with three doors, the central door has a sculpture of a human head with a trident akin to Shiva. At the other end of the gable, this sculpture is missing. In the back wall between the pilasters, images are not carved. The roof covering above the top floor is large, vaulted, and wagon-shaped, with arches at the corners. The top of the vaulted roof is fitted with a series of nine vase-shaped finials each consisting of a pot and trident.
Features
There are 18 inscriptions in Grantha and Nāgarī scripts of the Sanskrit language inscribed on its west portico. Out of the fourteen verses in these inscriptions, the twelfth verse is ascribed to Narasimhavarman I's grandson, Paramesvaravarman I, surnamed Atyantakama, who as the Pallava king was known as Atyantakama, Atyantakama-Pallaveshvara-Griham. Other verses are in praise of Shiva.
