Hiran Ruchi is named after a local Thai Buddhist temple 'Wat Hiran Ruchi', a third-level royal temple of the Worawihan typle. Originally named Wat Noi. It is believed that it was built by wealthy Chinese Ngoen (father-in-law of King Rama II) during the reign of King Taksin circa 1778.

There is an ordination hall in the temple with the architecture of the reign of King Rama I which is Thai mixed with Chinese style. There are large six stūpas, wooden stūpa. A Buddha statue in the attitude of subduing Mara, named Luang Pho Dam is a principal Buddha statue.^[2]

• Ban Lao Community, also known as Bang Sai Kai Community, it has a population of over 1,000. Originally, the ancestors of the community migrated from Kingdom of Vientiane (now Vientiane, Laos) during the early of Rattanakosin period. Ban Lao is well known among the musicians who play Thai instruments, as being a source that produces extremely good quality khlui (Thai wooden flute). Originally, the people of Ban Lao only made khlui to play in their community, until around 1960s they have taken it up as a profession. But nowadays, only a handful of households still produce khlui. Ban Lao is a community located behind Bansomdejchaopraya Rajabhat University (BSRU) along canal Khlong Bang Sai Kai. The community has Wat Bang Sai Kai, also known as Wat Lao as the centre. Pla som (pickled fish) is a unique food of community.^[6][5]
