The Main Shrine Hall of Buddha was completed in 1970. It is a seven-span structure with a double-eaves gablet roof, adopting Ming and Qing's palatial architectural design. The Eighties of the last century witnessed a close and intimate relationship between Hong Kong's Buddhist order with the Mainland, and this has in no small measure facilitated the building of the Tian Tan (Altar of Heaven) Big Buddha, the construction work of which had commenced in 1981 and was completed in 1993, and Di Tan (Altar of Earth). Both have followed the design of Tian Tan's Hall of Prayer for Good Harvests, including that of the base platform. They have also incorporated the engineering and technological expertise of China's National Space Administration. The completion of the Big Buddha has indeed laid a major architectural milestone for the monastery. It also exemplifies the monastery's leading role and influence in religious orders and tourism.
