Once known as the Powell Street Grounds, this park was opened in 1902 by the second mayor of Vancouver, and was eventually given his name. In the 1930s, the park was the only place where political gatherings could be held, and was consequently the location for many Depression-era demonstrations. Today, it caters to Vancouver's downtown eastside, serving as a recreational and social centre for the community. Its facilities include softball grounds, a basketball court, children's playground, and community centre. Another highlight of the park is the Powell Street Festival, an annual mid-summer event celebrating Asian-Canadian culture.
