Belváros (Inner City) Church is the oldest building in Pest side of river in Budapest. It was built in 1046 as a grave of Bishop St. Gellért (c. 980-1046), a missionary from Italy who played an instrumental role in converting Hungary to Christianity. According to tradition, he was martyred by angry pagans who rolled him down a hill across the river, which was named Gellért Hill in his honor.
The first church constructed on this spot was a 12th-century Romanesque structure built inside the ruined walls of the Roman fortress of Contra-Aquincum. In the early 14th century, after destroyed by Mongols, this church was replaced by a Gothic church which still stands today. It has been frequently renovated and remodeled in accordance with contemporary fashions, so its medieval origins are not obvious at first glance.
During the reign of Ottoman Empire Belváros was used as a mosque and in 1702 it was returned as a Christian church by Jesuits. The Rococo style pulpit dates from 1808.
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.
