Għar Ħasan is a karst limestone cave located along the southern coast of Malta, in the vicinity of Ħal Far within the limits of Birżebbuġa. One of the longest caverns on the island, it consists of several interconnected passageways which lead to two window-like openings in the cliff face along with a rock-hewn chamber which was excavated at an unknown date. The earliest evidence of human activity within the cave dates back to the Bronze Age, and while traces of pigments along some cave walls have sometimes been interpreted as poorly-preserved cave paintings these have never been definitively dated and it is doubtful whether they are of prehistoric origin.
