Most of what would later become the city of Aventura was initially developed during the 1970s as a high-rise residential area by Turnberry International Realty, when the area was still mostly swampland known as Biscayne Gardens. Some of the Miami area's tallest condominium towers are located there.
Aventura is also home to Aventura Mall, also developed and owned by Turnberry. The enormous success of the mall encouraged explosive growth in the area, and on November 7, 1995, the City of Aventura was incorporated.
