The Roman bridge of Córdoba was originally built in the early 1st century BC across the Guadalquivir river, though it has been reconstructed at various times since. Most of the present structure dates from the Moorish reconstruction in the 8th century.
Currently, after the Islamic reconstruction, has 16 arcades, one fewer than originally, and a total length of 247 meters. The width is around 9 meters.
The Via Augusta, which connected Rome to Cádiz, most likely passed through it. During the early Islamic domination the Muslim governor Al-Samh ibn Malik al-Khawlani ordered a bridge to be built on the ruins of what was left of the old Roman construction. In the Middle Ages, the Calahorra Tower and the Puerta del Puente were built at the bridge's southern and northern ends, respectively (the latter is now a 16th-century reconstruction). The bridge was reconstructed and expanded to its current size. The arches depict the famous Moorish architecture that dominates the city's scenery. In the 17th century, a sculpture depicting St. Raphael was put in the middle of the bridge, executed by Bernabé Gómez del Río.
During its history, the bridge was restored and renovated several times (in particular in the 10th century), and now only the 14th and 15th arches (counting from the Puerta del Puente) are original.
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.
