for architectural decoration. Park workers helped him load the most ornate pieces he could find, and they were hauled away. Not told of the arrangement, Burke discovered that Davis had taken some of the chapter house stones, and the museum board insisted these be returned. Davis was left with 58 stones from other monastery buildings. In 1983 and 1987, Davis made unsuccessful requests for all of the chapter house stones. After the 1989 Loma Prieta earthquake, the de Young museum was to be rebuilt, and the future of the stones was reconsidered. In September 1993, museum director Harry Parker joined with Davis to sign an unconditional permanent loan of the chapter house stones to New Clairvaux. In 1994, the city approved the loan with the stipulation that the building be restored accurately and that it be occasionally open to the public. The stones were transported in 20 truckloads to Vina. Inside an old brick barn built by Stanford to make brandy, the stones began to be fitted together, laid flat on Burke's plywood templates. Ground was broken in 2003 on the site of an orchard () next to the main cloister building. Architect Patrick Cole of Arcademe, overseeing the rebuilding project, said that there were more than half of the required stones for the chapter house. Of the missing stones, more than 90% were repeating-pattern stones with available templates to carve replacements. Stonemasons Oskar Kempf and Frank Helmholz used modern hydraulic lime as mortar rather than making their own as was done in the Middle Ages. Helmholz said of the opportunity offered by the project that it was "something most stonemasons don't do in all their career." The strength of the building is twice what it was in Spain, with the stones supporting their own weight as designed, augmented by an external framework of steel and concrete to hold them together when the California ground shakes. Contractor Phil Sunseri said that the building foundation was earthquake resistant as well; with a three-foot-thick (1 m) mat of concrete and steel underneath, such that "the entire building will move as one unit." The reassembled chapter house is the largest example of original Cistercian Gothic architecture in the Western Hemisphere, and it is the oldest building in America west of the Rocky Mountains. Nearby Sierra Nevada Brewing Company partnered with the monks of New Clairvaux to make a series of Belgian-style beers under
