The Roman quarry of El Mèdol was first excavated during the period of the Roman Republic and the Roman Empire. Its dimensions are over 200m wide and 10 to 40 deep. It was used to build the most important buildings of Tarraco (Colonia Iulia Urbs Triumphalis Tarraco, current Tarragona), capital of Hispania Citerior. At the centre remains a "witness column" (a column made of intact original rock) frequently found in Roman quarries. The quarry can be visited easily from the National Road 340 or from the AP-7, by La Mora.
