Excavations at the theater began in the 1980s and have been conducted by a team from Dokuz Eylul University since 2016. The work has shown that the site was not used solely as a performance venue.
Archaeologists have identified evidence of later religious buildings, churches, burial grounds, and tile kilns around the theater.
This year's excavations began in July and have focused on an area south of the theater, where researchers uncovered the skeletal remains of nearly 20 individuals.
In an interview with Anadolu, Meric said the burials appeared to be individual graves dating mainly to the Byzantine era.
The bodies were generally buried facing east, with their hands placed over their stomachs, a pattern consistent with Christian burial practices, she said. The graves were found about 1 meter (3 feet) below the surface, with some located above another grave and others alone.
Researchers found few objects buried with the individuals, including several beads, she said.
The bones were documented and transferred to an excavation facility for cleaning, analysis, and further study. Specialists from McMaster University in Canada, Rutgers University in the US, and universities in Türkiye are also involved in research at the site.
