"Playground apparatus was installed in 1928, and tennis courts in 1931. The Wrightwood Avenue Improvement Club petitioned for a fieldhouse, but none was built until 1954. Cragin Park is named for the surrounding neighborhood, which in turn took its name from a 19th-century industrial suburb."

"The Northwest Park District began to acquire land for Blackhawk Park in 1916. In 1921, renowned landscape architect Jens Jensen, designer of much of the West Park system, developed a plan for the park. Early improvements included a wading pool, a playground, tennis courts, and electric lighting. In 1926, the park district constructed a fieldhouse, one of six designed by Albert A. Schwartz for the Northwest and Old Portage Park Districts."
