Rose Atoll Marine National Monument

Rose Atoll Marine National Monument is a marine protected area surrounding Rose Atoll in American Samoa, featuring extensive coral reefs and deep ocean waters. The site encompasses vast stretches of sea with diverse underwater habitats and fish populations.

The atoll was discovered and named in 1819 by Louis de Freycinet during his voyage around the world. It was later designated as a protected monument to safeguard its fragile marine ecosystems.

The original Samoan name Motu O Manu means Bird Island, reflecting its role as a crucial breeding site for the region's seabirds. Visitors can observe this connection between the landscape and the animals that depend on it.

The monument is managed as a strictly protected reserve with regulations limiting human activity to preserve the marine environment. Access is restricted, and visiting requires special permission and coordination with local authorities.

The reef displays striking pink and reddish hues from abundant coralline algae that color the shallow waters. This distinctive coloration is what gave the atoll its name and makes it visually memorable.
