As a result of the exceptional discovery of Roman funerary stele, part of a wine press, and a large block of broccatello, we decided to study the quarries on the lower reaches of the Ebro River. The aim is to draw up an inventory of all the quarries, to identify possible ancient workings and to gain an accurate knowledge of the uses to which the quarried material was put. In general, the location and characteristics of the different deposits greatly facilitated their exploitation. Moreover, their proximity to the Ebro River made transportation very cheap. In the case of broccatello, shipment by sea was made easier by the proximity of the port of Tortosa.
