In the 1920s, William K. Vanderbilt II casually offered his yacht to Miami real-estate tycoon Carl Fisher in exchange for ownership of Fisher’s man-made island.

Today, that island is known as the richest ZIP code in the US, according to Bloomberg, and it’s celebrating its 100th birthday this month.

Fisher Island is a members-only enclave off the coast of Miami, where the average income of residents is $US2.2 million and the median home value is roughly $US2.7 million.

As Business Insider’s Katie Warren previously reported, to become a member, you must pay a $US250,000 fee and $US22,256 in annual dues in addition to purchasing a multimillion-dollar condo in one of 30 luxury condominium towers.

The 216-acre island can only be accessed by private shuttle boats, features sand imported from the Bahamas, has eight restaurants, a golf course, 18 tennis courts, two marinas, a K-8 school, and more.
