The rectangular burial chamber extends from northeast to southwest. Here, too, four pairs of supports form the long sides, which - as usual, but in contrast to tomb A - also correspond to four capstones. From the entrance in the southeast, only the southern supporting stone remains in situ. The dimensions of the chamber are 7 x 2.2 m. The tomb was scientifically investigated in 1924 by K.H. Jacob Friesen.
