These days, the staff of the museum-reserve, within the framework of the work plan for visual inspection of the technical condition of the object of cultural heritage with photo-fixation of the object of cultural heritage with visual changes in the structure, in accordance with the schedule of rounds, monitored the core-shaped mausoleum of the architectural complex “Tyarsh”.
The object has a round base and cone-shaped top with a crowning spire, located 75 meters east of the towers.
The height of the monument is 3.40 meters, on the south-western side there is a trapezoidal shaped trapdoor.
Employees of the “Archaeological Center named after E.I. Krupnov” note that the burial chamber of the mausoleum contained the remains of 9-10 deceased (partly in wooden coffins), as well as a variety of belongings. At the base of the chamber a stone box with a rectangular shape with slightly convex long sides was built on lime mortar. Its edges go under the base of the masonry walls of the mausoleum, which clearly indicates the sequence of construction of the monument. The stone box is oriented along the line NW-SE. The burial inventory allows to date it not earlier than the end of the XVII century.
The mausoleum was permanently investigated by R.A. Dautova in 1982. Restoration works were carried out on the monument.
