In the heart of the island's capital, Hagåtña, sits an impressive modern building—the Guam Museum (officially the Senator Antonio M. Palomo Guam Museum). It is the primary cultural repository for Guam, dedicated to preserving and sharing the unique heritage of the CHamoru people.

The museum is a grand three-story structure spanning over 4,000 square meters. Its archives house a massive collection of 250,000 artifacts, documents, and photographs. The building's architecture blends harmoniously into the historic landscape of Skinner Plaza, sitting alongside ancient ruins and the cathedral.
The centerpiece is the permanent exhibition, "The Journey of the CHamoru People." This interactive space uses modern technology, audio narratives, and rare exhibits to bring the island's 4,000-year history to life—from creation myths to contemporary challenges.
