This small, dank, roofless tomb has beautiful engravings
of overlapping sets of concentric circles
which are similar to petroglyphs at Fuente de la Zarza, La Palma (Canary Islands).
Unfortunately, they have deteriorated since this photo was taken in the nineteen-seventies.

The effect is similar to that of a comb on wet clay.
