Abstract (EN): The paper presents the results of an experimental investigation of the fatigue crack growth in plane specimens made from puddle iron. Eiffel Bridge from Portugal and 19th-century viaduct steel member from Poland. The tests were performed under the load ratios R = 0.05, 0.1 and 0.5. There were also considered the different description of fatigue crack growth rate using strain energy density parameter based on cyclic J-integral. The fatigue crack growth rate in the tested material is significantly higher than its "ancient" equivalent i.e. old 19th-century mild steel. There is also a noticeable strong contribution of the crack closure effect.
