There is a story told that this iron fence was ordered on behalf of King Rama III from the United Kingdom by Somdet Chao Phraya Borom Maha Prayurawong. It was intended to be used as the wall surrounding the Grand Palace but King Rama III did not take the offer. Then Somdet Chao Phraya Borom Maha Prayurawong asked for the iron fence to be erected around Wat Prayurawongsawas instead.
