First sighting of Koror, Babeldaob, and Peleliu recorded by Westerners
was by the Spanish expedition of Ruy López de Villalobos at the end of January
of 1543. They were then charted as Los Arrecifes (The Reefs in Spanish).
In November and December of 1710 these three islands were again visited and
explored by the Spanish missionary expedition commanded by Sargento Mayor Francisco
Padilla on board of the patache Santísima Trinidad. Two years later they
were explored in detail by the expedition of Spanish naval officer Bernardo de
Egoy.
