The plaque reads: "Flagler Park, formerly known as City Park, has been an important public space in West Palm Beach since the founding of the community. The town site for West Palm Beach was laid out in 1893 as a grid pattern of streets running north-south and east-west. The only variation was at the eastern end of Clematis Street, where two angled, short streets branched off to create a triangular public common area.
Over the years, the site has seen a variety of uses. Downtown merchants organized impromptu ball games on the park-like grounds when business was slow. In 1900 a two-story frame building was donated for use as a reading room and transported across Lake Worth from Palm Beach. It was placed on the southeastern portion of the parcel.
The Woman's Christian Temperance Union dedicated a drinking fountain in the Park in 1907. In 1915, a Woman's club was placed on the parcel. Other amenities were also added to the park including a shuffleboard court and a bandstand for outdoor concerts.
As the city's population expended during the 1920s the facilities of the Reading Room were outgrown and a library was built in 1923. It opened in January 1924 as the Memorial Library, named to honor the dead of World War I. It too was outgrown and was replaced by another library in 1962. In 1994 the library was remodeled and the plaza in front of the library was redesigned, incorporating a triangular in-ground fountain. This forecourt has become the center of downtown activities, continuing the traditional use of this important civic space."
