Elk Rock Garden

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 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. Dunthorpe is an unincorporated community on the west side of the Willamette south of Portland and north of Lake Oswego along Oregon Route 43.
