The Cypress House, originally located on Longboat Key, is now a small military museum. It was built using pecky cypress, a decorative wood type. The holes in the wood are apparently caused by the growth of a fungus in the living tree.
The Heritage Station Post Office, built in 1880, was Palmetto's first free-standing post office. When it was built, mail still came to Palmetto by steamship from Cedar Key. The post office was moved here in 1982, and was the first building the Palmetto Historical Park. On Heritage Day each year, you can mail letters from this post office, each one getting a special hand cancellation.
A prominent feature of the historical park is the 1914 Carnegie Library, which over the years has also served as Town Hall, the school library, and the Girls Club. Today it houses a local history library. The current public library is across the street.
The Manatee County Agricultural Museum and Hall of Fame is also at the Palmetto Historical Park.
The park and agricultural museum are free if you just want to walk around (donations welcome), and tours are available.
