The temples of West Bengal
were built in a noticeable style called ‘Bengali style’, a 'hybrid' form of planning. Chala, Ratna and Dalaan styles are three major classifications of the above style.
Chala style architecture, also known as Hut style, developed all over the state at the beginning of the 15th century. The temples built in this style have curved Bangla roof and curved cornice. Do-Chala (two roof surfaces) and Char Chala (four roof surfaces) are two verities of this architecture.
Jor Bangla Temple at Bishnupur is an example of the Chala style architecture. Here, a small tower gives stability and strength to the twin sloped roofs.
