The Amphitheatre of Durrës was built in the beginning of the 2nd century AD. It was used for performances until the 4th century AD. The earthquake of 345/346 likely damaged the monument and closed it. An early Christian chapel was constructed on the amphitheatre in the second half of the 4th century. The chapel was initially decorated with frescoes; in the 6th century, mosaics were added. A medieval chapel was built in the 13th century, also decorated with frescoes. The amphitheatre was covered over in the 16th century, after the Ottoman occupation, when the wall was built nearby. In 2004 the University of Parma started restoration work to save the monument.
The amphitheatre has an elliptical shape with axes of 132 metres and 113 metres. It is built on a slope of the hill, and inside the amphitheatre there are staircases and galleries at different levels. The chapel with mosaics is preserved. The site currently functions as a museum.
It is the largest amphitheatre ever built in the Balkan Peninsula with once having a capacity of 20,000 people. The amphitheatre is included on the tentative list of Albania for inscribing it as a UNESCO World Heritage Site.
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.
