The "Big Four Building", built in 1852, was home to the offices of Collis Huntington, Mark Hopkins, Leland Stanford, and Charles Crocker. The Central Pacific Railroad and Southern Pacific Railroad were founded there. The original building was destroyed in 1963 for the construction of Interstate 5, but was re-created using original elements in 1965. It is now a National Historic Landmark. Also of historic interest is the Eagle Theatre (Sacramento, California), a reconstruction of California's first permanent theatre in its original location.
