The Da Ponte Fountain dates from 1666, replacing an older one on the same site. Its superstructure is in the shape of a bridge, surmounting an octagonal water basin surrounded by fifteen pilasters, each bearing the arms of local noble families who had contributed funds toward the fountain.
A subaquatic aqueduct connected the island of Koper to the mainland as early as the end of the 14th century. By the 16th century, the 10,000 inhabitants of the city were facing a water shortage, rainwater cisterns having become inadequate. In the 17th century, Niccolò Manzuoli recorded the city water supply, noting that a 2-mile distant spring at Colonna was piped to the island via wooden underwater tubes, some of which have been unearthed during excavations by modern archeologists.
The water spurts from four mascarons at the base of the arch. The fountain was used as a source of potable water until 1898.
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.
