Arch of Trajan in Mérida was an entrance arch, possibly to the provincial forum. It was located in the Cardo Maximus, one of the main streets of the city and connected it to the municipal forum. Made of granite and originally faced with marble, it measures 14 metres high, 5.7 metres wide and 8.7 metres internal diameter. It is believed to have a triumphal character, although it could also serve as a prelude to the Provincial Forum. Its name is arbitrary, as the commemorative inscription was lost centuries ago.
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.
