The so-called Great Basilica was the principal church in late antique Butrint and sections of a 6th century mosaic floor are still preserved. The church was erected on the site of a cistern belonging to the Roman city’s aqueduct and is over 30m long. It followed the characteristic plan and architectural devices prevalent throughout Epirus, employing a central nave flanked by aisles that were screened from the nave by closed colonnades.
At the east end was a tripartite transept and a central pentagonal apse. Remains of the mosaic pavement include trailing ivy tendrils and scrolling guilloche that are also found in the Baptistery, indicating that these two religious monuments are broadly contemporary. The devices are characteristic of mosaicists working in Nikopolis in northwestern Greece. Some time later, most likely in the 13th century when Butrint began to boom once more, the Great Basilica was extensively rebuilt and effectively became Butrint’s cathedral.
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.
