Belle Isle is a neighborhood in the city of Miami Beach on an island in Biscayne Bay, Florida, United States. It is the easternmost of the Venetian Islands, a chain of artificial islands in Biscayne Bay in the cities of Miami and Miami Beach. It is home to apartment buildings, a portion of the Venetian Causeway, a city of Miami Beach park, and a hotel. It is between Rivo Alto Island and the main barrier island of Miami Beach. History Belle Isle was originally called "Bull Isle", and was later renamed. Unlike the other Venetian Islands, Belle Isle is not completely artificial. Like the Sunset Islands, Belle Isle was originally a rough mangrove hammock island sitting in north Biscayne Bay near the Miami barrier islands, before the use of the term "Miami Beach". Before fruit farmer John S. Collins partnered with the wealthy investor Carl G. Fisher to build the Collins Bridge from Miami in 1913, the new luxury properties under development in Miami Beach and Collins' large avocado orchards were inaccessible except by ferry boat. When Collins dug the Collins Canal, work crews deposited dredged sand around the rough island at the mouth of the canal, increasing its land mass and defining its shape. The "improved" island, now cleared of mangroves and platted into small parcels of land for single-family homes, extended into Biscayne Bay and allowed Collins and Fisher to build a relatively short wooden bridge across the bay by running the road over Belle Isle. The gateway to Miami Beach earned a reputation as an enclave for fashionable millionaires, such as Joseph H. Adams, whose sprawling estate occupied the southeast corner of the island. During the Florida land boom of the 1920s, Belle Isle and Fisher's nearby Flamingo Hotel were the site of the famous Biscayne Bay Speed Boat Regattas. Fisher had successfully promoted automobile races in Indianapolis, and he used his skills to stage gasoline-powered speed boat races in the smooth waters of Biscayne Bay just south of Belle Isle as a spectacle to attract the wealthy and sophisticated tourists that he was seeking as a target audience for his new exotic vacation destination. In 1942, the University of Miami turned a boat house on the Joseph H. Adams estate into the first "Marine Lab" for the Rosenstiel School of Marine and Atmospheric Science. Belle Isle was also the site of the All Souls Episcopal Church
