Pioneer Park is a 4.89-acre (19,800 m2) park crowning the top of Telegraph Hill in San Francisco. It was established in 1876 in celebration of the United States Centennial. Prior to establishment of the park, it was the site of the Marine Telegraph Station. The main feature of the park, Coit Tower, was completed in 1933 using a $100,000 bequest left to the city by Lillie Hitchcock Coit in 1924. A bronze statue of Christopher Columbus was placed in the park in 1957, donated by the city's Italian-American community.
