Raywood, formerly named Arbury Park, is a property in the Adelaide Hills, South Australia. The 17-room Georgian-style house was constructed in 1935 to designs by Kenneth Milne for noted South Australian and Federal politician, Sir Alexander Downer, who built the house and developed the formal garden as a setting akin to an English estate. Both the house and gardens (the latter truncated by construction of the South Eastern Freeway), are heritage-listed.
