Look how much closer to Nicaragua and other countries than Colombia's mainland itself! 

So San Andres is an island that Christopher Colombus himself is said to have visited between 1492 and 1500. In the late 16th century the Dutch used the island as a safe haven from pirates and smugglers but the first real settlement came in 1628 when the British arrived. Did our former Empire know no bounds!?

Admittedly it is pretty cool to hear the older generation speak English in that famously well-known Caribbean accent.
