In 2010, Flagler College and the University of Florida (UF) were awarded a <i>Save America’s Treasures</i> grant by the National Endowment for the Humanities to preserve and provide access to architectural drawings for the National Historic Landmark Hotel Ponce de Leon (1885-1887) and the Memorial Presbyterian Church (1889-1890) in St. Augustine, Florida. During this two-year project, the UF Smathers Libraries is conserving and digitizing an irreplaceable collection of the earliest architectural drawings of the Carrère &Hastings firm. The drawings were created for the oil and railroad tycoon Henry Flagler beginning in the 1880s, but the majority of the drawings subsequently had been “lost” for decades. The few people who knew of their existence were unaware of their historical significance, and the drawings remained stored for years in a boiler room under high Florida temperatures and humidity, and exposed to insects and rodents.
