About the flag and history of Guam

Guam Flag Icon

Territorial flag is dark blue with a narrow red border on all four sides; centered is a red-bordered, pointed, vertical ellipse containing a beach scene, a proa or outrigger canoe with sail, and a palm tree with the word GUAM superimposed in bold red letters; the proa is sailing in Agana Bay with the promontory of Punta Dos Amantes, near the capital, in the background; blue represents the sea and red the blood shed in the struggle against oppression note: the US flag is the national flag.

Spain ceded Guam to the US in 1898. Captured by the Japanese in 1941, it was retaken by the US three years later. The military installation on the island is one of the most strategically important US bases in the Pacific.
