Rosario House is one of only a few residential structures in Hagåtña to survive WWII. Edith Rosario Blankenfeld, the daughter of Carolina Duenas Flores Rosario, lived in the house prior to WWII (Moore et al. 1993). She recalled that her mother, born in 1894, inherited the house from her parents who had inherited it from their parents. Mrs. Blankenfeld’s father served in the U.S. Navy. According to Mrs. Blankenfeld, prior to WWII the house had a tiled roof, ifit wood floors, and screened windows with shutters.

MARS excavated three units placed near three different corners of the Rosario House lower wall or bodega (basement). The objectives of the archaeological work were to determine whether previous structures had been built on the site, to obtain a sample of artifacts which would provide information about activity patterns at the site, and to obtain a comparative collection of historic ceramics (see Bulgrin 2010 for descriptions of the historic ceramics recovered during the excavations) and other historic materials.

Three postholes were exposed near the bottom of Excavation Unit 1, located near the southeast corner of the mamposteria foundation. A piece of wood recovered from one of the postholes was submitted for radiocarbon dating. It provided a calendar date of approximately A.D. 1750, which would indicate when the post was 172 ! ・ 2nd Marianas History Conference 2013
