Chino’s Post Office, 5375 Walnut Ave., is a grabber. I like the decorative pillars, which link horizontally toward the top. Very mod. The facade sign that reads “United States Post Office, Chino California 91710” is cool too.
The facility opened in 1970. It says so right on this plaque by the entrance. I took a peek at the interior and it was drab, although the air conditioning was vigorous.
