On the southern edge of the Kog tower complex stands the Tusholi (Kog-Erdy) sanctuary dedicated to Tusholi. According to radiocarbon analysis, it was built in 1441-1486. In the sanctuary for a long time there was a wooden image of the patroness of fertility and childbirth, with a bronze mask depicting a severe female face. With the cult of fertility and childbirth was associated and another monument – a four-sided column in human growth, crowned with a removed stone mushroom head. When it did not rain for a long time, the mountaineers filmed it, and set it up only after the precipitation began. This object, like another pillar-shaped sanctuary in the Kog region, has not survived to our days.
The sanctuary of Tusholi (Kog-Yerdy) is part of the Dzhirakh-Assin State Historical, Architectural and Natural Museum-Reserve and is an identified object of cultural heritage protected by the state.
