Yi Tai Study Hall is situated at Shui Tau Village, Yuen Long. It was built by the Tang clan of Kam Tin who came to settle in this fertile plain as far back as the 11th century. According to local legends, Yi Tai Study Hall was built towards the end of Daoguang reign (1821-1850) to accommodate the two immortals, Man Cheong and Kwan Tai (literary and martial gods respectively). Both were originally worshipped in a fung shui pagoda erected nearby to boost scholarship but the pagoda was later demolished.

Subsequently, a group of 16 local scholar-gentry formed a society called the Tang Yi Tai Wui (The Tang Society of the Two Immortals) for the construction and operation of a new study hall which was named Yi Tai Study Hall, i.e. study hall of the two immortals. The building was built purely for use as a study hall and its architecture is therefore simple and functional. Restoration work was completed in 1994. The building is now open to the public.
