Gremyachevskii karst caves are the moves Gremyachevskii catacombs, which are located in the Novomoskovsk district, near the village Gremyacha, on the banks of the river Talakovka (formerly Arapova) at the foot of the cliff, they laid in quartz sandstones. Gremyachevskii caves also known under the name Kapowski caves.

There are several versions of the origin of these caves. Gremyachevskii cave called Gremyachevskii catacombs: part of the fortifications Gremyachiy Ostrog (fortress Gremyachaya), in the late 16th-early 17th centuries together with Epifascial the rocks that covered the weak areas of Large defense line South of Venev. This hypothesis is quite doubtful, but, overall, the General direction coincides with the location of the village Gremyacha, which is about 6 km away. there is Also a version that here was the abode of ancient people.

The most reliable version is the assumption that the caves were dug in the 19th century by local farmers for solitary prayer, for this reason they are also called Kapowski cave monastery. Work on the digging of caves have been initiated by Yakov Pavlov, a pious peasant from the village Gremyacha Starokozache settlement in 1849, who wished to create something like the caves of Kiev-Pechersk Lavra. This idea was picked up by his comrades: Vasily Nikitin and Ivan Kobzev. Over time, the underground chapel has become increasingly popular among local farmers. Rather questionable is the fact that in caves the service was held in the rooms does not contain elements of Church architecture (altar, pulpit, gates, etc.), size of the rooms is quite small.

Survived the first map of these caves with the documents of the investigation, which was undertaken by order of the Tula Governor in 1855. The reason for the proceedings was the complaint of the priest of the village Gremyacha, who spoke about the Exodus of parishioners and the falling revenues of the Church. The official reason, probably could be a suspicion in the activities of the sect of the "whips", which then gained momentum. After investigation, March 12, 1856, was issued an order to deny access to the caves and destroy them, but, obviously, failed.

Gradually the river Arapuca washed away at the shore, down to the forest above the caves, sandy sediments and landslides have compounded the destruction of the caves. As of today are little more than 200 km of underground tunnels, which require visitors quite a caring attitude.

To the entrance to the main cave-monastery trail, which runs between the two shafts, which are formed by the remnants of the cave walls and later learned the breed. On the slope is a large Sandstone boulders. The entrance to the cave is a hole with a height of 1 m and a width of 0. 5 m, which goes down at a slight angle.

The cave is a system of correct narrow passages, which can be passed in full growth. The most spacious part of the cave has been preserved. The far side was closed by a landslide. Till our days there were several "cells" with a size of 2x2 m, and the room-"the Church" sizes 2x5 m and height 3 m. In some places there are niches Desk of Sandstone.

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