This marked building is not the Visitor Center. It is a vacant building which was at one time a sanatorium hospital and then later (in the 1970s) used as a dormitory for volunteers by the United Farm Workers (UFW). The building immediately to the east that is currently titled National Chavez Center is the actual Cesar E. Chavez National Monument. That building (the smaller one tot he left) was owned by the NCC until 2012 when NCC donated this building (which contains Cesar Chavez' office and a museum) and Cesar and Helen's gravesite memorial gardens and their house to the US federal government. These properties  were donated for the National Park Service in order to establish the Cesar E. Chavez National Monument in 2012.
