San Sebastian Church

San Sebastian Basilica Minore might be the only "all" steel church in the world (in my research, I haven't seen a church that is of its architectural type). There is no understatement of it - the walls, columns, pilars, naive, ceilings, etc. are all made of metal. Aside from that, it is largely known as the only prefabricated church in the world. San Sebastian is a National Treasure and a National Historical Landmark, and is declared as one of the four most endangered sites in the Philippines. In fact, it has been in the 100 list of endangered sites in the world by the World Monuments Fund in 1998. Having seen other churches of lesser universal value around gaining WHS titles, there is no way that this neo-gothic church can be denied of a WHS designation.
