Gremyachevskie caves are moves Gremyachevskih catacombs, which are located in the Novomoskovsk district, near the village of Gremyacheye the River Tetyakovka (formerly Arapovka) at the foot of the cliff, they are laid in quartz sandstones. Gremyachevskie cave still known as Arapovo caves.

There are several theories about the origin of these caves. Gremyachevskie cave is also called Gremyachevskimi catacombs: a part of the fortifications Gremyachy Fortress (Fortress Gremyachaya), in the late 16th and early 17th centuries, along with the prison Epifanskie that covered the weak areas Large defense line south of Venev. This hypothesis is rather questionable, but, in general, the general direction coincides with the location of the village Gremyacheye to which about 6 km. There is also a version that here was the home of the ancient people.

The most accurate version is the assumption that the caves were dug in the 19th century by local peasants for solitary prayer, for this reason they are called Arapovo cave monastery. Work on digging caves were initiated by Yakov Pavlov, a pious peasant from the village Gremyacheye Starokozache settlement in 1849, who wanted to create something like the caves of Kiev-Pechersk Lavra. This idea was picked up by his friends: Vasily Nikitin and Ivan Kobzev. Over time, the underground chapel became popular among local farmers. Rather questionable is the fact that the services were held in caves: the rooms do not contain elements of church architecture (altar, pulpit, gates, etc.), Room size is quite small.

Save the first map of the caves with the documents of the investigation, which was undertaken by order of the governor of Tula in 1855. The reason for the complaint proceedings was the priest of the village Gremyacheye, who spoke about the outflow of parishioners and falling incomes of the church. The official reason, probably, could be suspected in the activities of the sect, "whip", which then gained momentum. As a result of the investigation March 12, 1856 issued an order to prohibit access to the caves and destroy them, but obviously, it was not possible to perform.

Gradually the river Arapovka coastal erosion, cut down forests on the caves, sand drifts and avalanches have exacerbated the destruction of caves. To date, it remained little more than 200 meters of underground passages that require visitors rather careful attitude.

The entrance to the main cave-monastery is the path that lies between the two shafts, which are formed by the remains of the cave walls and rock extracted later. On the slope - large blocks of sandstone. Entrance to the cave is a hole height of 1 m and a width of 0, 5 m, which goes down at a slight angle.

Caves - a system of regular narrow passages, which can take place in full view. The most spacious of the cave was not preserved. Further collapse of the closed. Have survived several "cells" having a size of 2x2 m, and the room- "church" is the size of 2x5 m and a height of 3 meters. In some places there is a niche, table of sandstone.

450 meters upstream Tetyakovki, on the same bank of the cave is a small-cell, which has a length of about 10 m.
