Now the Jessie Ball duPont Center, this former library was named for Haydon Burns, the longest-sitting mayor in Jacksonville's history. The library opened in November 1965. The 126,000-square-foot building is wrapped in hundreds of colorful tiles. The unique building was designed by Architect Taylor Hardwick. The exterior walls facing Ocean and Adams streets have 88 "fins" extending from the second floor to the roof, like the 88 keys on a piano. The fins catch the wind and cast shadows to help keep the building cool. The building recently underwent a major restoration, and now houses several Jacksonville nonprofits.
