Talking to Anadolu Agency, Mehmet Kulaz, deputy director of the excavation team said it was the biggest historical cemetery in the Islamic world.
He said more than 1000 tombstones have been cleaned and epigraphy analyses of 750 of them have been transmitted into an online database.
"It is possible to understand the importance of the city by looking at the tombstones. Vaults, mosques and other ruins are indications that Ahlat was a famous urban center in the past," he added.
First book encompassing drawings of the tombstones as well as analyses of epigraphy has been published. Kulaz said the preparations were on to release second and third volume for the benefit of researchers.
