The rare, deep pink marble in the dining room of Marble House is Numidian marble. It became very popular after the rediscovery of the quarries in the French Colonies of Algeria and Tunisia in the 19th century. Since Roman times, Numidian marble in pink, yellow, and white was used for victory monuments and in the homes of emperors, wealthy senators, and in the Pantheon. Of course Alva Vanderbilt insisted on using it at Marble House! Visit soon to see it for yourself: NewportMansions.org #newportmansions #preservationsocietyofnewportcounty #newport_mansions #newportri
