A notable local use for the iron from the Ynyscedwyn works was in the rebuild of Saint Cynog's Church, Ystradgynlais, which was completed in 1861. There, iron was used to create the pillars along the aisles, in a design allowing for a much lighter feel than many traditional churches, and one which allows worshippers to more easily look through and beyond the pillars to the pulpit or altar.
