HIALEAH, Fla. -- The National Trust for Historic Preservation on Thursday named Hialeah Park racetrack to its 2007 list of America's 11 most endangered historic places.

Hialeah Park was hailed as the world's most beautiful racecourse when it opened in 1925. The 2-acre park was host to former President Harry Truman and former British Prime Minister Winston Churchill, and served as the racetrack where Seabiscuit made his debut in 1935.

Known for its Mediterranean architecture, Hialeah Park was featured in the opening title sequence to the hit television series "Miami Vice" in the 1980s. The park's pink flamingos, also in the opening, still flock on the grounds. The Audubon Society has already designated it as a sanctuary for the American flamingo.

"The first time I saw this track was in 1942 and I fell in love with it," said Frieda Lieberman, a former park employee. "I think it's the most magnificent place."

Following lagging attendance, racing came to an end there in 2001. After Hurricane Wilma damaged buildings on the property in 2005, Hialeah Park closed its doors permanently.

Last fall, the stables were stripped of their historic certification and demolished. Now, the privately owned park is threatened by a planned 3,760-unit condominium and apartment complex with nearly 1 million square feet of retail and 200,000 square feet of office space.

If the plan were approved, only a portion of the park would be preserved, angering some historians who argue it should be purchased by the city.
