In the aftermath of the California gold rush, discouraged gold seekers left the mineral regions to farm the rich creek bottom lands of southwestern Placer County, and these pioneers formed the nucleus of Roseville’s first families. Within a few years, railroads began to pass through the area, beginning with the California Central, whose rails reached the site of present-day Roseville in August 1861. In January 1864, the rails of the Central Pacific Railroad (CPRR) intersected those of the California Central at what railroad sources called the junction, and the town developed around it. Located in the heart of a rich agricultural area, the junction was well suited for a freight station along the Central Pacific’s right-of-way. O.D. Lambard recognized this and, on August 13, 1864, laid out a new but largely paper city called Roseville. The first building erected at Roseville Junction was a depot and freight shipping station at the Y formed by the junction of the northbound and eastbound lines of the CPRR. Around the depot and the railroad, Roseville slowly developed, with two streets on opposite sides of the main line of the CPRR emerging as its business and commercial centers. One of these thoroughfares, Pacific Street, lies in the heart of today’s Old Town, and the only building remaining from those early years is the three-storied brick International Order of Odd Fellows Building.
