A church at the site of current San Giovanni Maggiore Basilica was likely erected sometime in the 4th century. There are a number of founding legends for the church. One is that emperor Constantine Ifounded the church in gratitude for the rescue of his daughter Costanza from a shipwreck. It may have been built or introduced into a pre-existing pagan temple dedicated to the cult of Hercules or Hadrian. One of the stones in the architrave is dated to 324. The church underwent numerous reconstructions, including in the 6th century. It was likely made into a Byzantine-style basilica during the era of Belisarius.
After an earthquake in 1635, the last reconstruction in 1656 led to the Baroque building by Dionisio Lazzari seen today. He designed the present cupola, completed in 1685. Further earthquakes in 1732 and 1805 required more reconstructions.
The 1870 earthquake devastated the church and knocked down the roof. For the restoration, Gennaro Aspreno Galante was unable reconstruct the former details. Almost razed in 1872, the local canon Giuseppe Perrella commissioned a neoclassical reconstruction, completed in 1887, from engineer George Tomlinson, with help by Errico Alvino and Federico Travaglini. A hundred years later, the roof again caved down, closing the church again for 42 years, until a restoration in 1978 unveiled the early-Christian apse, below the wooden choir dating from the 17th century. The church was long closed for restoration and architectural studies.
The imposing main altar, damaged over the years, was built in 1743 by Domenico Antonio Vaccaro. Behind the apse is visible the ancient church apse.
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.
