Since 1991, the Centro Studi Sotterranei of Genoa has conducted the exploration, survey and documentation of rock-cut and underground structures located in different regions of Turkey. The Ka.Y.A. project was begun in 2007, with the goal of the identification and the study of rock-cut sites around Ahlat in eastern Turkey, as completion of major archaeological excavations in the ancient city located on the northern shores of Lake Van. It is a vast area, at an altitude between 1,700 and 2,500 m.a.s.l. and wedged between massive volcanic systems. During the four years of research the team documented 395 rock-cut sites most of which date back to medieval and post-medieval times and relating to different cultures and religions: Armenian, Seljuk, Ilkhanid, Kara Koyunlu, Ak Koyunlu, and Ottoman. The results of the first survey campaign were completed in 2007 and published as BAR S2293 (2011). That volume is now supplemented by the data obtained during the second season in 2008, with the hope to publish as soon as possible the results of the subsequent missions completed in 2009 and 2010.
