The Island of Guam is situated in the Pacific Ocean, and is the southernmost and largest island in the Mariana island chain. As the westernmost (unincorporated) territory of the United States. Guam is a truly cosmopolitan community with a unique culture, the core of which is the ancient Chamorro, heavily influenced by the Spanish occupation and the Catholic Church. In addition to the indigenous Chamorros and stateside Americans, Guam boasts large populations of Filipinos, Chinese, Japanese, Koreans, and Micronesian Islanders, as well as a few Vietnamese, Indians, and Europeans. Spanish influence may also be seen in the mestiza, a style of women's clothing, or in the architecture of Guam's southern villages.
