The chamber is usually round, and may have two or more niches in its circumference. It is roofed by the successive overlapping or corbelling of the upper courses. The vault thus formed is further supported by a pillar of wood or stone set in the centre of the chamber. On the walls of some of the chambers there are traces of rough painting in red. The whole tomb is covered with a circular mound.
The chambers are built of upright slabs and are roofed by corbelling. Cairn H covered a corridor leading to a chamber and opening off on each side into a side-chamber, the whole group thus being cruciform. In these chambers were found human remains and objects of flint, bone, earthenware, amber, glass, bronze, and iron.
The parapet on this wall is unlike that at the top of the presbytery and choir walls. It has no corbelling and no arched and cusped work; it is merely a plain piece of walling, slightly overhung with a weathered coping at the top and a moulded string beneath. The general features in the design of the north end of this transept are similar to those of the south.
The walls in one case stood high enough to show, from the corbelling of their upper courses, that the huts were roofed in the same fashion as the nuraghi themselves. Another village, that which surrounds the nuraghe of Su Chiai, was protected by a wall of huge stones. It is thus clear that the nuraghi were the fortified centres of the various villages of Sardinia.
Cyclopean walls of huge irregular stones. Also good square-cut masonry. 'Corbelling' system for arches, each layer of stones projecting inwards over the one below. Also used for the vaults of 'Beehive' Tombs towards end of period. Geometric or Dipylon Period. Pottery. Iron Age. circ. 1000 B.C. Absolute break in continuity from what preceded. No naturalism. Not much variety.
At the first glance it is a barn built of millions of bricks; but if you give it time it grows into a most beautiful Gothic church with lovely details, such as the corbelling under the eaves, the borders of the circular windows, and still more delightful borders of the long windows, and so forth; while its campanile is magnificent.
A doorway just large enough to be entered with comfort leads through the thickness of the wall into a round chamber roofed by corbelling, with the assistance sometimes of one or more pillars. Section and plan of the Talayot of Sa Aquila, Majorca. Nau d'Es Tudons, plan and section. The naus or navetas are so named from their resemblance to ships. The construction is similar to that of the talayots.
Occasionally there are spaces between successive slabs, and these are filled up with dry masonry. The roof is made either by laying large slabs across the tops of the sides or by corbelling with smaller slabs as at Stoney Littleton. The two best known examples of this are the tumuli of Avening and of Rodmarton.
This tumulus conceals a long gallery leading into a rectangular chamber. The walls of this latter are built of horizontal courses of stones, except at the corners, where there are tall, vertically-placed slabs. The chamber has three niches or recesses, one on each of its closed sides. The roof is formed by corbelling the walls and finishing off with slabs laid across.
Buildings in which this system is used are occasionally roofed with slabs, but more often corbelling is employed. At a certain height each succeeding course in the wall begins to project inwards over the last, so that the walls, as it were, lean together and finally meet to form a false barrel-vault or a false dome, according as the structure is rectangular or round.
