The Merizo Conbento is a 19th-century stone building that served as the residence of the Spanish colonial priest attached to the Dulce Nombre de Maria church. It is listed on the US National Register of Historic Places as one of the best-preserved examples of Spanish-Chamorro colonial architecture in Guam.
The building is constructed of thick limestone and mortar in a simple two-storey form typical of Spanish mission architecture in the Pacific. It survived World War II and subsequent decades of development largely intact. Today it stands as a quiet reminder of the three centuries of Spanish administration that shaped Guam's language, religion, and culture before the American period began in 1898.
