The chairman of the Chemin de Fer du Nord railway company, James Mayer de Rothschild, chose the French architect Jacques Ignace Hittorff to design the current station. Construction of the new complex was carried out between May 1861 to December 1865; the new station actually opened for service while still under construction during 1864. The façade was designed around a triumphal arch and used many slabs of stone. The building has the usual U-shape of a terminus station. The main support beam is made out of cast iron. The support pillars inside the station were made at Alston & Gourley's ironworks in Glasgow in the United Kingdom, the only country with a foundry large enough for the task.
