American publisher William Randolph Hearst bought parts of the monastery in 1931 with the intention of using its stones in the construction of a grand and fanciful castle at Wyntoon, California, but after some 10,000 stones were removed and shipped, they were abandoned in San Francisco for decades. These stones are now in various locations around California: the old church portal was erected at the University of San Francisco, and the chapter house was reassembled by Trappist monks at the Abbey of New Clairvaux in Vina, California. Other stones are serving as simple decorative elements in Golden Gate Park's botanical garden.
