The <I>Trulli</I> of Alberobello

<p>The <em>trulli</em> , limestone dwellings found in the southern region of Puglia, are remarkable examples of drywall (mortarless) construction, a prehistoric building technique still in use in this region. The <em>trulli</em> are made of roughly worked limestone boulders collected from neighbouring fields. Characteristically, they feature pyramidal, domed or conical roofs built up of corbelled limestone slabs.</p>
