Very little if any of Carmel actually dates from the colonial period. Probably the only building that does is the restored Carmel Mission built by Father Junipero Serra in 1770. All children going through the California public school system learn about the California missions and I was no exception. My Dad took us on a special trip just to see the Mission.
Because these new reproduction buildings are already 80 years old, they have acquired a certain patina that lends an air of authenticity.
