The first undersea park in the U.S., John Pennekamp Coral Reef State Park encompasses approximately 70 nautical square miles. While the mangrove swamps and tropical hammocks in the park's upland areas offer visitors a unique experience, it is the coral reefs and their associated marine life that bring most visitors to the park.

Established in 1963, John Pennekamp Coral Reef State Park was the first undersea park in the United States. John Pennekamp Coral Reef State Park, and near by Florida Keys National Marine Sanctuary, cover approximately 178 nautical square miles of coral reefs, sea grass beds much more. The park extends 3 miles into the Atlantic Ocean and is approximately 25 miles in length. These areas were established to protect and preserve a portion of the only living coral reef in the continental United States. The park was added to the National Register of Historic Places on April 14, 1972.The park contains a wide variety of tropical vegetation, shore birds and marine life. While the mangrove swamps and tropical hammocks offer visitors a unique and interesting experience, it is the coral formations and associated marine life that most park visitors come to enjoy with its most famously known for the underwater Christ Monument.

 John Pennekamp from originally from Cincinnati, Ohio but moved to Miami and became a newspaper editor, whose efforts contributed to the establishments of Everglades National Park and the preservation of what would become John Pennekamp Coral Reef State Park.There have been many efforts through the government in selling land in south Florida was a big deal.The Florida Land Boom of the 1920s extended the salable land of Miami area westward into the eastern Everglades. Soon new land to sell began to run out about the time that John Pennekamp came to Miami which was year 1925. In 1957, the condition of the outer reefs off of the Keys and its shoreline were reaching crisis level and Dr. Gilbert Voss, professor of marine biology along with 52 other scientists pursued into saving the reefs. John Pennekamp, as chairman of the Florida Board of Parks and Historic Memorials approved the 75 square mile section of the reef - 10% of the entire reef - as a permanent preserve as 'the preservation of coral reefs is necessary'.On December 10, 1960, Governor Collins at Harry Harris Park dedicated and named the coral reef preserve "John D. Pennekamp Coral Reef State Park" although the dedication program was titled: "Dedication of Key Largo Coral Reef Preserve" after the organization Coral Reef Preserve was given control of bottom to the 3 mile limit.

This article beings to explain the history being the creation of John Pennekamp and why it is such a great site fro history, touring and simply helping the earths ocean wildlife.Dr. Gilbert Voss of the Marine Institute of the University of Miami, first became aware of the extent of damage occurring to the reef structure during his studies of the marine species in the Keys. 

The coral reefs that took thousands of years to form, were quickly decimated by thoughtless vendors. Dr. Voss then suggested that a no-more-profitable scientific project could be undertaken than the protection of this area.
