The seafaring Chamorro people originally settled the Mariana Islands over 3,500 years ago, sailing large outrigger canoes know as "proas" from Southeast Asia. Around 1,000 years ago, they began constructing two-piece megalithic pillar structures out of limestone. These "latte stone" creations still exist on several Mariana Islands. Although they have endured centuries of change, the Chamorro spirit lives on in its people. Today their descendants predominantly use the Chamorro language and continue to preserve their culture and traditions.
