In the centuries immediately following the Roman empire, even the marble of Aurisina lives a dark period, but it remains one of the most used stones in the near Venice.
With the commercial development of Trieste, due to the proclamation of Free Port, the marble of Aurisina once again became the protagonist of new constructions in cities such as Palazzo Pitteri, the Stock Exchange building and other prestigious examples.
It is with the birth of the Austro-Hungarian empire that the marble of Aurisina has its golden age, finding wide use in Trieste and every part of the reign as for the Imperial Palace of Vienna, the Budapest Parliament and the Opera of Graz.
While Aurisina marble is used in all the most important cities of the reign (Linz, Innsbruck, Graz, Munich, Salzburg, Ljubljana, Prague, Rijeka…) the quarries and the laboratories of Karst count over 3000 workers.
After Trieste annexation to Italy, the marble of Aurisina is chosen for the Military Memorial of Redipuglia and the Central Station of Milan. For the first time, it arrives overseas countries and is used in Egypt and the USA.
