Platted from 1912 to 1936, the Mango Promenade Historic District was one of West Palm Beach's earliest upper-middle class suburbs, significant for its history and variety of architectural styles. The district featured early accommodations for automobiles, with garage outbuildings built contemporaneously and in matching style to the main houses. Unique to the district were two pedestrian walkways, Mango Promenade, linking South Dixie Highway to South Olive Avenue, and Orange Court, linking South Dixie Highway to South Flagler Drive; each served as an entrance walkway for houses on either side, while garage entrances were placed on parallel alleys. South Dixie Highway contained commercial buildings, making the area a true mixed-use district. West of South Dixie Highway stood the former African American cemetery operated from 1902 to 1921 by the Lakeside Cemetery Association; the land was donated to the City of West Palm Beach in 1921 and converted to a park named Flamingo Park. The district became a local historic district in 1995 and was listed on the National Register of Historic Places in 1999. It includes residences dating from the 1910s and 1920s mixed with later development, with a homogeneous grouping of mostly wood vernacular bungalows and two-story hip-roof American Foursquare houses. Many houses have sleeping porches, wide front porches, detailed rafter tails, shingle or clapboard siding, and large double-hung windows. Several show strong Prairie-style overtones, including broad eaves, horizontally grouped windows, high belt lines, chunky three-quarter-height porch columns, and strong horizontal emphasis, in the mold of Frank Lloyd Wright and the firm W.G. Purcell and G.G. Elmslie, and would have been considered avant-garde in their day. Other residential styles include Craftsman Bungalow, Colonial Revival, Mediterranean Revival, Mission Revival, Monterey, Queen Anne, Shingle, Dutch Colonial, and vernacular. Along South Dixie Highway, mercantile buildings from the early 1920s reflect the Mediterranean Revival style then prevalent in the city generally, and commercial construction halted because of the land bust in 1926 and hurricanes in 1926 and 1928.
