The National Rose Gardens are located in Parkes Canberra, Australia, at the sides of Old Parliament House at the side of the Senate and the House of Representatives.
The four rose gardens are part of the Old Parliament House Gardens themselves, and were established in the 1930s.
The gardens declined after the Parliament moved to the new Parliament House in 1988, as they were unnoticed behind hedges and gates.
