Opa-locka is a city located in Miami-Dade County, Florida, United States. As of the 2010 U.S. Census, the population was 15,219. The city was developed by Glenn Curtiss. Developed based on a One Thousand and One Nights theme, Opa-locka has the largest collection of Moorish Revival architecture in the Western Hemisphere, and streets with such names as Sabur Lane, Sultan Avenue, Ali Baba Avenue, Perviz Avenue, and Sesame Street. Opa-locka has an area of 4.2 square miles (11 km2; 2,700 acres) and is located in the northeastern area of Miami-Dade County, Florida.
The name Opa-locka is an abbreviation of a Seminole place name, spelled Opa-tisha-wocka-locka (or Opatishawockalocka), meaning "wooded hummock" or "high, dry hummock."
Opa-locka was founded by aviation pioneer Glenn Curtiss in 1926. Curtiss developed the city with a Moorish architecture theme. While the 1926 Miami hurricane badly damaged the city and brought the Florida land boom to a halt, several Moorish-style buildings survived. Twenty of the original Moorish Revival architecture buildings have been listed on the National Register of Historic Places as part of the Opa-locka Thematic Resource Area.
Amelia Earhart launched her historic trip around the world from Miami Municipal Airport, just south of Opa-locka. The famous German dirigible Graf Zeppelin visited Naval Air Station Miami, which later became Opa-locka Airport, as a regular stop on its Germany-Brazil-United States-Germany scheduled route.
In the 1950s, the airport - specifically Building 67 - became the site of a large CIA operation, PBSuccess, run by operatives including E. Howard Hunt.
