Auguste Perret in the context of "Théâtre des Champs-Élysées"

Eugène Emmanuel Viollet-le-Duc (French: [øʒɛn vjɔlɛ lə dyk]; 27 January 1814 – 17 September 1879) was a French architect and author, famous for his restoration of the most prominent medieval landmarks in France. His major restoration projects included Notre-Dame de Paris, the Basilica of Saint Denis, Mont Saint-Michel, Sainte-Chapelle, the medieval walls of the city of Carcassonne, and Château de Roquetaillade in the Bordeaux region.

His writings on decoration and on the relationship between form and function in architecture had a fundamental influence on a whole new generation of architects, including all the major Art Nouveau artists: Antoni Gaudí, Victor Horta, Hector Guimard, Henry van de Velde, Henri Sauvage and the École de Nancy, Paul Hankar, Otto Wagner, Eugène Grasset, Émile Gallé, and Hendrik Petrus Berlage. He also influenced the first modern architects, Frank Lloyd Wright, Mies van der Rohe, Auguste Perret, Louis Sullivan, and Le Corbusier, who considered Viollet-le-Duc as the father of modern architecture. English architect William Burges claimed that "We all cribbed on Viollet-le-Duc even though no one could read French".

Le Havre is a major port city in the Seine-Maritime department in the Normandy region of northern France. It situated on the right bank of the estuary of the river Seine on the English Channel southwest of the Pays de Caux, very close to the Prime Meridian. Le Havre is the busiest port on the northern French Coast and largest container port in France. it is the second largest city in the Normandy region of France with total population of the greater Le Havre conurbation being smaller than that of Rouen.It is also the second largest subprefecture in France, after only Reims. The name Le Havre means "the harbour" or "the port". Its inhabitants are known as Havrais or Havraises.

The city and port were founded by King Francis I in 1517. Economic development in the early modern period was hampered by religious wars, conflicts with the English, epidemics, and storms. It was from the end of the 18th century that Le Havre started growing and the port took off first with the slave trade then other international trade. After the 1944 bombings the firm of Auguste Perret began to rebuild the city in concrete. The oil, chemical, and automotive industries were dynamic during the Trente Glorieuses (postwar boom) but the 1970s marked the end of the golden age of ocean liners and the beginning of the economic crisis: the population declined, unemployment increased and remains at a high level today.

Amiens (English: /æˈmjæ̃/ or /ˈæmiənz/ AM-ee-ənz; French: [amjɛ̃] ; Picard: Anmien, Anmiens or Anmyin) is a city and commune in northern France, located 120 km (75 mi) north of Paris and 100 km (62 mi) south-west of Lille. It is the capital of the Somme department in the region of Hauts-de-France and had a population of 135,429, as of 2021. A central landmark of the city is Amiens Cathedral, the largest Gothic cathedral in France. Amiens also has one of the largest university hospitals in France, with a capacity of 1,200 beds. The author Jules Verne lived in Amiens from 1871 until his death in 1905, and served on the city council for 15 years. Amiens is the birthplace of French president Emmanuel Macron.

The town was fought over during both World Wars, suffering significant damage, and was repeatedly occupied by both sides. The 1918 Battle of Amiens was the opening phase of the Hundred Days Offensive which directly led to the Armistice with Germany. The Royal Air Force heavily bombed the town during the Second World War. In the aftermath, the city was rebuilt according to Pierre Dufau's plans with wider streets to ease traffic congestion. These newer structures were primarily built of brick, concrete and white stone with slate roofs. The architect Auguste Perret designed the Gare d'Amiens train station and nearby Tour Perret.

The Église Notre-Dame du Raincy (Church of Notre Dame du Raincy) is a Roman Catholic church in the commune of Le Raincy near Paris. It was built in 1922-23 by the French architects Auguste Perret and Gustave Perret. The edifice is considered a monument of modernism in architecture, using reinforced concrete in a manner that expresses the possibilities of the new material.

St. Joseph's Church, Le Havre is a Roman Catholic church in Le Havre, France. From 1945 to 1964, the City of Le Havre commissioned Auguste Perret and his studio to head the rebuilding of the entire city after it had been completely destroyed by the British during World War II. St. Joseph's was built between 1951 and 1957/58 as part of this reconstruction. It acts as a memorial to the five thousand civilians fallen and the usual sanctuary dedicated to a patron saint; in this case Saint Joseph, fittingly the patron saint of a happy death, fathers, workers, travelers, and immigrants.

The church was designed by the chief architect for the reconstruction of Le Havre, Perret, who was the teacher and mentor to the Swiss architect Le Corbusier. A centrally-planned building, Saint Joseph's Church was envisioned as a beacon for the city. The church's single, central tower dominates the city skyline, easily visible from the city's port. Perret's vision created a building resembling a lantern, now fondly referred to as the "lantern tower" or the "lighthouse at the heart of the city". Made of concrete, St Joseph's is a product of modern architectural innovation in Post-War France. The tower is 107 meters tall and acts as a beacon visible from out at sea, especially at night when illuminated.
