The Columbus Museum's Bradley Olmsted Garden was designed for homeowner W.C. Bradley by the Olmsted Brothers firm of Massachusetts, founded by the American landscape architect Frederick Law Olmsted. Of the thirteen residential projects the firm worked on in Georgia, including others in Columbus, this garden is widely recognized as the most substantial and significant. Its shaded ravine, formal and informal pools, cascading waterfall, pecan grove, and Japanese yew and crape myrtle walkways typified the more naturalistic gardens that became popular after the close of the Victorian era. Azaleas, camellias, dogwood, iris, roses, and forget-me-nots were among the many blooms planted between 1925 and 1928. Bradley took great interest in the garden and corresponded frequently with William B. Marquis, the firm's lead Columbus designer. At Bradley's request, the firm transformed an 1880s trolley station on the property into a pool house, the only remaining structure from that line. The garden is part of the Wynn's Hill-Overlook Historic District, listed on the National Register of Historic Places.
