Statement of Significance (as of designation - April 19, 1993):
Edward Bok's Mountain Lake Sanctuary and Singing Tower were created as the ultimate gift he could present to the people of America, his adopted land. A native of the Netherlands, Bok came to fame as the editor of The Ladies' Home Journal; he was also a Pulitzer Prize-winning author, local and national civic leader, and philanthropist. The Sanctuary and Tower were dedicated, on Bok's behalf, for visitation by the American people by President Calvin Coolidge on February 1, 1929. The gardens were designed by F. L. Olmsted.
