He said excavation and restoration efforts, carried out year round under the authority of the Turkish Culture and Tourism Ministry, are continuing at full speed.
Beçin was once the capital of the 13th century Menteshe Beylik, or principality, one of the frontier principalities established by the Oghuz Turks.
The city holds layers of history, including previous discoveries of graves from the Chalcolithic period, indicating uninterrupted settlement for around 5,000 years.
Pektaş added that further excavation will continue around the castle's grave and bath areas, with more arrowheads expected to be found.
He also highlighted ongoing work at the so-called "Persian Tower," where objects dating back to the sixth century BC have been unearthed.
