Under Napoleon III, a new wave of urbanism and architecture was given birth; extravagant buildings such as the neo-baroque Palais Garnier were built. The urban planning of the time was very organised and rigorous; most notably, Haussmann's renovation of Paris. The architecture associated with this era is named Second Empire in English, the term being taken from the Second French Empire. At this time there was a strong Gothic resurgence across Europe and in France; the associated architect was Eugène Viollet-le-Duc. In the late 19th century, Gustave Eiffel designed many bridges, such as Garabit viaduct, and remains one of the most influential bridge designers of his time, although he is best remembered for the iconic Eiffel Tower.
