The Arizona Historical Society maintains 3 adobe buildings which are listed on the National Register of Historic Places. The Sanguinetti House Museum was constructed in the 1870s and was purchased in 1890 by pioneer merchant E.F. Sanguinetti. He added to the home as his family grew and created an Italian oasis with a garden and bird aviaries, which are maintained today. The house contains exhibits and period rooms, which tells the history of the lower Colorado River region from the 1540s to the present. The museum also provides numerous educational opportunities. Next door is the Adobe Annex. Constructed in 1873, it was the home of steamboat captain Jack Mellon. Today it houses the museum's library and archives collections, as well as the gift shop. Two doors away is the Molina Block, constructed in 1875 as a buisness building. It is currently undergoing rehabilitation to serve as a future museum site for the Society. Tax deductible donations for this project are always welcome.
