Elk Rock Gardens of the Bishop's Close are located on a hillside estate overlooking the Willamette River in Dunthorpe, Oregon, in the United States. Peter Kerr started the gardens in 1916 on a 13-acre estate that passed to the Episcopal Diocese of Oregon after his death in 1957. The estate includes a manor house and other structures, and is open to the public. Magnolias and other native and non-native trees, shrubs, and plants grow in the gardens.
