Visit Santa Rosa’s “Old Town” Historic Railroad Square for unique shopping, dining and charming ambience in the heart of Santa Rosa. Railroad Square was honored with a listing on the National Register of Historic Places in 1979 because of its preservation efforts for restoring and preserving the significant architectural buildings that represent the influence the railroad had on a community. When the first trains arrived in Railroad Square in the 1870’s, the focus of the town turned to the hustle and bustle around the Depot. Railroad Square is excited that the Sonoma-Marin Area Rail Transit (SMART) has begun passenger rides from Downtown San Rafael to Santa Rosa, with the main Santa Rosa station being in Railroad Square. This has made it easy – and fun! – for visitors from Marin County and beyond to come to Sonoma County for short trips for shopping, entertainment, and more.
