The Arc de Triomphe de l'Étoile is one of the most famous monuments in Paris. It stands in the centre of the Place Charles de Gaulle (originally named Place de l'Étoile), at the western end of the Champs-Élysées. It should not be confused with a smaller arch, the Arc de Triomphe du Carrousel, which stands west of the Louvre. The Arc de Triomphe honours those who fought and died for France in the French Revolutionary and the Napoleonic Wars, with the names of all French victories and generals inscribed on its inner and outer surfaces. Beneath its vault lies the Tomb of the Unknown Soldier from World War I.
The triumphal arch was commissioned in 1806 after the victory at Austerlitz by Emperor Napoleon at the peak of his fortunes. Laying the foundations alone took two years and, in 1810, when Napoleon entered Paris from the west with his bride Archduchess Marie-Louise of Austria, he had a wooden mock-up of the completed arch constructed. The architect, Jean Chalgrin, died in 1811 and the work was taken over by Jean-Nicolas Huyot. During the Bourbon Restoration, construction was halted and it would not be completed until the reign of King Louis-Philippe, between 1833 and 1836, by the architects Goust, then Huyot, under the direction of Héricart de Thury. On 15 December 1840, brought back to France from Saint Helena, Napoleon's remains passed under it on their way to the Emperor's final resting place at the Invalides. Prior to burial in the Panthéon, the body of Victor Hugo was exposed under the Arc during the night of 22 May 1885.
The monument stands 50 metres in height, 45m wide and 22m deep. Its design was inspired by the Roman Arch of Titus. The Arc de Triomphe is built on such a large scale that, three weeks after the Paris victory parade in 1919 (marking the end of hostilities in World War I), Charles Godefroy flew his Nieuport biplane through it, with the event captured on newsreel.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
