The two-story brick building at 1000 2nd Street, at the corner of 2nd and J Streets in Old Sacramento, was built in 1852. It was the western end of the Pony Express during its brief run from 1860 to 1861.
It was declared a National Historic Landmark in 1966 and is California Historical Landmark No. 606. Part of Old Sacramento State Historic Park, it now houses a museum on the history of Wells Fargo.
