Morocco, too, has its dolmens, especially in the district of Kabylia, while near Tangier there is a stone circle. Off the north coast of Africa, and thus on the highway which leads from Africa to Europe, lie the Italian islands of Lampedusa and Linosa. The latter is volcanic in origin, and its surface presents no opportunity for the building of megalithic monuments. Lampedusa, on the other hand, consists of limestone, which lies about in great blocks on its surface. On the slopes of the south coast there are several remains of megalithic construction, but they are too damaged to show much of their original form. However, on the north side of the island there are megalithic huts in a very fair state of preservation. They are oval in form and have in many cases a base course of orthostatic slabs. Some miles to the north of Linosa lies the much larger volcanic island of Pantelleria, also a possession of Italy. Here megalithic remains both of dwellings and of tombs have been found. On the plateau of the Mursia are the remains of rectangular huts made of rough blocks of stone. These huts seemed to have formed a village, which was surrounded by a wall for purposes of defence. In the huts were found implements of obsidian and flat stones used for grinding. [Illustration: FIG. 20. Plan of the Sese Grande, Pantelleria. (Orsi, _Monumenti Antichi_, IX.)] The tombs of the people who inhabited this village are, unlike the houses, circular or elliptical in form. They are locally known as _sesi._ The smaller are of truncated conical shape, the circular chamber being entered by a low door and having a corbelled roof. In one of the _sesi_ a skeleton was found buried in the contracted position. The finest of the tombs, known as the Sese Grande, elliptical in form (Fig. 20), has a major diameter of more than 60 feet, and rises in ridges, being domed at the top. It contains not one chamber, but twelve, each of which has a separate entrance from the outside of the _sese._ To judge by the remains found in the _sesi_ they belong entirely to the neolithic period.
