Elk Rock Gardens of the Bishop's Close

Elk Rock Gardens of the Bishop's Close is a historic 13-acre (5.3 ha) hillside estate garden in Dunthorpe, Oregon, just south of Portland, perched on cliffs above the Willamette River. Peter Kerr started the gardens in 1916 on an estate that passed to the Episcopal Diocese of Oregon after his death in 1957. The private estate includes a manor house-inspired residence and other structures, and is open to visitors Monday - Friday, 8:00 am – 5:00pm. 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.
