three dolmen-like chambers lie on either side of a central passage, and
a seventh at the end opposite to the entrance. The whole is constructed
of upright slabs of stone, and is surrounded by a circle formed in the
same way.

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.
