It was later used for different purposes, including as a military warehouse, archive, theater hall and vocational school, he told Anadolu.
The museum's display and arrangement work is more than 80% complete, and officials plan to open it soon.
Talaslı said the restoration was based on archival photographs, documents and oral histories of people who had lived in the area.
"We will create a museum on the ground floor, where we will tell about the city's tangible and intangible cultural heritage," he said.
Visitors will be able to learn about İncesu's history, architecture, notable figures, archaeology, gastronomy, agriculture and grape production.
They will also see artifacts, including ceramics unearthed at the nearby Orensehir archaeological site, Talaslı said.
