It is estimated that 300\u2013400 of these staples can be found throughout the building. A radiocarbon-based dating method indicated that six clamps were used in the cathedral\u2019s original construction in 1163 and not during renovations in the eighteenth and nineteenth centuries. The conclusions suggest Notre-Dame was the first cathedral to use iron extensively, while others from the same era used wooden arches. Built over more than half a century, the church was once the tallest building in the world at 32 m high. The nave is 37 m wide and 125 m long.
