One of the most popular things to see and do in Castroville is to take the Historic Walking Tour which features over 50 homes and commercial structures originally built in the mid to late 1800s.
You will notice that the buildings on the Walking Tour are identified with a distinctive marker - a silhouette of a typical house bearing the name and the date of construction. You will also find them elsewhere, as the Chamber of Commerce has presented them to all homeowners who have researched the records to verify the necessary information. Look for them as you move about the city and surrounding countryside. History is everywhere!
