At the beginning of the 16th century, several Indian peoples lived in what is now Costa Rica. On his fourth voyage to the “New World”, Columbus set foot on September 18, 1502 near present-day Puerto Limon. The Native Americans treated him with respect, and during his 17-day stay, Columbus noticed that some of the Native Americans were carrying gold objects. The Spaniards therefore thought that there would be a lot of gold in the interior and therefore called the country Costa Rica, which means "rich coast".
