The Chechen State Historical, Architectural, and Natural Museum-Reserve is a nature reserve located in the southern part of the Chechen Republic within the Vedeno Nature Reserve, encompassing the entire Itum-Kali and Sharoi districts and parts of the Achkhoy-Martan, Vedeno, and Shatoi districts. It was established on June 2, 1988, by decree of the Council of Ministers of the RSFSR. Its area is 233,800 hectares. It's safe to say that the Chechen Nature Reserve is an open-air museum. It encompasses the historical and natural monuments of the Argun Gorge. Among the natural monuments within the Chechen Museum-Reserve, the most notable is the Sheki-Khyekh Cave, home to sulfur springs and a hydrogen sulfide river. The cultural and historical sites include approximately 150 tower complexes from the early and late Middle Ages, religious buildings, military and residential towers, early Muslim burial sites, cyclopean structures, and other historical monuments. Many of the museum-reserve's buildings are in ruins.
