The travertine which forms round the springs of the Sarno was used even at Pompeii as building material.
There is good travertine below Tivolj and elsewhere in Italy; the finest granite is found at Baveno.
Calcareous tufa or travertine occurs in the valley of Matlock and elsewhere, and in some places is still being deposited by springs.
Pamphylia consists almost entirely of a plain, extending from the slopes of Taurus to the sea, but this plain, though presenting an unbroken level to the eye, does not all consist of alluvial deposits, but is formed in part of travertine.
Other noteworthy tombs are those of the Granduca, with a single subterranean chamber carefully constructed in travertine, and containing eight sarcophagi of the same material; of Vigna Grande, very similar to this; of Cone Casuccini (the ancient stone door of which is still in working order), with two chambers, containing paintings representing funeral rites; of Poggio Moro and Valdacqua, in the former of which the paintings are almost destroyed, while the latter is now inaccessible.
