Porte d'Aix (also known as the Porte Royale) is a triumphal arch in Marseille, marking the old entry point to the city on the road from Aix-en-Provence. The classical design by Michel-Robert Penchaud was inspired by the triumphal arches of the Roman Empire. The Porte d’Aix was initially conceived in 1784 to honour Louis XVI and to commemorate the Peace of Paris (1783) that ended the American Revolutionary War. Following the restoration of the Bourbon monarchy in 1814-15, the project was resumed in 1823, now to commemorate French victories in the Spanish Expedition, notably at the Battle of Trocadero, August 31, 1823. It was eventually completed in 1839, with a more general theme of victory.
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.
