Used extensively on the facades and pavement at the Getty Center as well as at the primary plaza levels at the Getty Villa, travertine is a visible architectural and aesthetic component at both locations. While both types of travertine used were taken from quarries near Rome, they differ slightly in age and appearance. The travertine at the Center is approximately 8,000 to 80,000 years old, whereas the variety used at the Villa dates back about 2,220 years. The Villa’s travertine also appears slightly darker than its Center counterpart. Travertine was integrated into the Villa construction in a conscious effort to draw a material reference to the Getty Center—thus creating a sense of continuity between these two visually distinct museums.
