The Ernest Hemingway House was the home of the Nobel Prize winning Ernest Hemingway for ten years and was where he did a lot of his writing. The house is architecturally beautiful and unique, but one of the most interesting things about the house may be the 40 cats that roam the grounds and are descendents of one of Hemingway's own extra-toed pet cats.

The Key West Shipwreck Museum tells the story of Key West's shipwrecks through historic artifacts, actors and films. Also featured is the rediscovery of the Isaac Allerton ship that had sunk off the key in 1856 and, when discovered in 1985, was the richest shipwreck in Key West's history!

Southernmost Point is a giant, colorful buoy that serves as a marker for- you guessed it- the southernmost point in the continental United States.
