There are stones walls that are built punctiliously without using clay in the mouth of Daichin Mountain, covered with pine and larch forests and located in the confluence of Bayan and Oglogch rivers, which are in the west of Batshireet Somon center. These walls are called Oglogch Kherem. Width of these walls is nearly 3m and there are tracks of two gates in the wall and remains of embarks inside the walls. The remains of wall stones can be seen clearly in the southeastern and eastern walls but not in other walls because they are almost disappeared. Thickness of the wall is 2 m, heights are 2.5-4.5 m in average and 3.1 m in highest parts. Locals call a lanky rocky cliff inside the wall as a horse rope of Chinggis qahan. There are no remains of buildings in the wall but flat terraces, thus, it could be archers’ fortification of the 12-13th century.
