The Northwestern Pacific Railroad's passenger depot at Santa Rosa was originally built in 1904 to replace the previous one which had burned. Besides serving duty as a depot, the station also starred in Alfred Hitchcock's Shadow of a Doubt, which was shot on location in Santa Rosa. As with other railroad passenger depots, this one faded into abandonment when the NWP ceased passenger operations.
Today, the building serves as both a historical reminder of Santa Rosa's past, as well as housing the Santa Rosa Convention and Visitors Bureau and the California Visitors Center. They have a few railroad artifacts on display for visitors.
