The word Antilles comes from a time before European conquest and domination, which means Phantom Islands. Puerto Rico includes the smaller Islands of Vieques, Culebra, Mona, Desecheo and Caja de Muertos. These Islands complete the archipelago. Other than the main island only Vieques and Culebra are inhabited year round.
