Sea Lion Park was a 16-acre (65,000 m2) amusement park started in 1895 on Coney Island by Paul Boyton. He fenced the property and charged admission, the park becoming the first enclosed and permanent amusement park in North America. Up until the establishment of this park, amusement areas around the country consisted of pay-as-you-go concessions. In 1903, Sea Lion Park was replaced by Luna Park.
