Al Jassasiya may appear to be just a deserted quarry—and it is—but look carefully and you’ll find a wealth of mysterious petroglyphs. First reported in 1956 by Danish archaeologist Peter Glob, a total of more than 900 rock carvings can be found at this surprising site.
The petroglyphs of Al Jassasiya were first studied in 1964. The most common motifs are round holes reminiscent of cup holders, and what they represent is unknown. Some are carved in seemingly random order, while others are in patterns, such as rows, double rows, and rosettes. Aside from the round holes, there are also carvings of dhows, fish, scorpions, ostriches, and quadrupeds.
