Old Town Tustin is an area centered around a group of historic buildings located on Main Street and El Camino Real which date back to the 1880s.
Among the early businesses and structures in Tustin were a blacksmith shop, a combined grocery store/meat market, a business and feed store building, churches and school buildings. The present day museum is located in a historic old building which has housed many businesses over the decades.
Main Street runs from Williams Street on the west to just past Newport Avenue on the east. Today, its one-and-a-half miles reveal over twelve decades of Tustin's past. Tourists are advised to park their cars and follow a map to "Take Main Street to Tustin History."
