National Park Service Lists Peter and Laurie King Kerr Estate in the National Register of Historic Places

The Peter and Laurie King Kerr Estate (now known as Elk Rock Garden) is among Oregon's newest entries in the National Register of Historic Places. Oregon's State Advisory Committee on Historic Preservation (SACHP) recommended the nomination at its June 2026 meeting for the property's significance, in the areas of architecture and landscape architecture, as a rare surviving Portland area example of a turn-of-the-century country estate. The National Park Service, which maintains the National Register, accepted the nomination in late August 2026.

Located on the outskirts of South Portland, the Peter and Laurie King Kerr Estate was designed and constructed between 1897 and 1957 and it still reflects the layered contributions of its owner, grain commission merchant Peter Kerr, and several prominent design professionals, including landscape architects John C. Olmsted and Adolph Meyer, horticulturalist Emanuel T. Mische, and architects Ellis F. Lawrence and William Holford, the designers of the Kerr residence located on the grounds. Now open to the public, the Peter and Laurie King Kerr Estate stands as one of the Portland area's only country estates or large private gardens that retains much of its original scale, setting, and design.

The National Register of Historic Places

The National Register of Historic Places is maintained by the National Park Service under the authority of the National Historic Preservation Act of 1966. Properties listed in the National Register are:

• Recognized as significant to the nation, state, or community;
• Considered in the planning of federal or federally assisted projects;
• Eligible for certain federal and state tax benefits;
• Qualified for historic preservation grants when funds are available;
• Eligible for leniency in meeting certain building code requirements;
• Subject to local laws pertaining to the conservation and protection of historic resources.

State law in Oregon requires local governments to offer a minimal level of protection for properties listed in the National Register of Historic Places; decisions about how to accomplish that goal reside with local governments, which also have the authority to create and regulate local historic districts and landmarks.
