Together with the two other marble towns, Borba and Vila Viçosa, Estremoz is internationally known for its fine to medium marble that occurs in several colours: white, cream, pink, grey or black and streaks with any combination of these colours. Especially the pink marble (Rosa Aurora and Estremoz Pink) is in high demand.
This marble has been used since Antiquity as a material for sculpture and architecture. The first exports in Roman times were probably for the construction of the Circus Maximus of Emerita Augusta, in modern-day Spain. The Portuguese navigators exported this marble to Africa, India and Brazil. The marble from this region was used in famed locations such as the Monastery of Jerónimos, the Monastery of Batalha, the Monastery of Alcobaça and the Tower of Belém. Portugal is the second largest exporter of marble in the world, surpassed only by Italy (Carrara marble). About 85% of this marble (over 370,000 tons) is produced around Estremoz.
