Portoro is a very precious and luxurious marble form Italy, more precisely from the area of Portovenere near the city of La Spezia in Italy.
Portoro is a marble with a deep black background and golden-yellow veins which was already used for construction purposes in ancient times. It had its first peak during the Roman Empire, when it was mainly used in the city of Luni where we can still find one of the large streets the so called Cardo-Decamanus paved completely in Portoro and some little blocks are incorporated in the walls of the amphitheater (1st century before Christ). In the Middle Ages Genoa started using Portoro for facades, columns, internal wall cladding etc. The second peak was reached during the Renaissance and Baroque period when Portoro became one of the famous stones used in religious architecture. Some of most known churches are: St. Peter’s Basilica in Rome, San Pietro in Vincoli (St. Peter in Chains) in Rome, San Paolo fuori le Mura (St. Paul outside the Walls) in Rome, the Baptistery of the Church of Sr. Mary in La Spezia, Jesus Church (Casa Professa) in Palermo etc.
Since the end of the 19th century Portoro has been exported to Europe and the USA (internal wall cladding of the Paramamount Home Theater).
