Kazvin has many baths and cisterns fed by underground canals.
It contains several cisterns, excavated in the rock.
The reburnt and cooled char is collected and sent back to the char cisterns.
A few fragments of undoubtedly Roman pottery and some Roman coins have been found there, but the cisterns and the ruins of houses are probably of later date (P. Calcara, Descrizione dell' Isola di Linosa, Palermo, 1851, 29).
There are no streams near the ruins, and the water-supply was derived from cisterns and from a few pools now filled with soil and vegetation.
