The Walker Zanger Reference Stone Collection is a cooperative project between the Center for Architectural Conservation at Penn and the Getty Conservation Institute. The Collection contains over 5,000 coupons of building stones used in both high-style and vernacular architecture, serving as a living repository of 20th-century and 21st-century stone materials for research and teaching. Current holdings include marbles, granites, limestones, slates, sandstones, onyx, agglomerates, alabasters, basalts, bluestones, and soapstones. It is supplemented by an online database set to be released in fall 2024.
The physical collection is split in two mirrored partitions. One is currently managed by the Getty Conservation Institute under the direction of Davide Gulotta, PhD, while the other by Penn’s Center for Architectural Conservation.
