It is part of the Angra dos Reis municipality in the state of Rio de Janeiro.
The most accepted hypothesis for the origin of the name abraão (not to be confused with the mistranslation "Abraham") relates to the term abra in old Portuguese, meaning "bay".
The development of Vila do Abraão gained momentum in the late nineteenth century, at the time of the Empire of Brazil, when a leper hospital was built nearby.
The attractions of the island supported the rapid development of tourism, transforming the town into a tourist hub.
Hostels, bars, and restaurants were constructed, and sea and land trails were developed connecting the town to the beaches and other attractions of Ilha Grande.
