Discovery Green is a public urban park in Downtown Houston, Texas, United States. Opened in 2008, Discovery Green 11.78acre is located on Avenida de las Americas across from the George R. Brown Convention Center and the Hilton Americas Hotel, adjacent to Toyota Center. The park includes a lake, bandstands and venues for public performances, two dog runs, a children's area and multiple recreational areas. The park was principally designed by the landscape architecture firm Hargreaves Associates.
The first event held at the park was Houston Mayor Bill White's 2008 inauguration. The park officially opened to the public on April 13, 2008. It is estimated that almost a quarter-million people visited the park between opening day and June 30, 2008. The estimates were made by comparing the size of crowds with the Houston Police Department's estimate of 30,000 people who went to the park on opening day.
