Incidentally, the church is that of San Sebastian, recognized by the UNESCO as the only all-steel church or basilica in Asia. It has also been implausibly reputed to be the first prefabricated building in the world, and more plausibly claimed as the only prefabricated steel church in the world.
Although this is unconfirmed in the official histories of the church, it has long been reputed that Gustave Eiffel, the French engineer behind the Eiffel Tower and the steel structure within the Statue of Liberty, was involved in the design and construction of San Sebastian Church.
