Commonwealth Park, Park in central Canberra, Australia

Commonwealth Park covers 34.25 hectares on the north shore of Lake Burley Griffin in central Canberra. Its present layout follows a 1964 master plan by British landscape designer Dame Sylvia Crowe, with small ponds and water features, walking trails, bike paths, sculptures and memorials. The outdoor Stage 88, which often holds concerts, stands within the park, and Regatta Point gives views across the lake to the National Gallery, High Court and National Library.

In 1874 Ebenezer Booth built a house on the glebe of St John the Baptist Church within today's park, east of Nerang Pool; Murray's store, the area's first retail store, operated there until it burnt down in 1923, and stunted pines and English elms remain on the spot. Walter Griffin's 1918 plan placed an "aquarium pond", now Nerang Pool, in a recreation area north of the lake, revised from his 1911 plan to reduce earthworks. A 1964 master plan by British landscape designer Dame Sylvia Crowe shaped the park's current form.

Commonwealth Park is best known for hosting Floriade, Australia's largest spring flower festival, held every year over about four weeks. During that time, the garden beds fill with tulips and daffodils, and the park also hosts concerts, markets, and workshops.

The park is free to enter at any time and has barbecue areas, picnic tables, and public toilets on site. Paths are paved and accessible for visitors with reduced mobility, making it easy to move around even with a pram or wheelchair.

Somewhere beneath Commonwealth Park lies a buried artwork called "Earthwork" by artist Bert Flugelman, made of shiny aluminium tetrahedrons placed underground in 1975 without a recorded exact location. No one knows precisely where it is, which means visitors walking through the park are unknowingly passing over a hidden sculpture.
