Have you ever noticed the small holes in brick walls of front porches? These seemingly simple features actually serve important purposes in architecture.

Before modern mailboxes, these holes also served as mail slots, letting letters be delivered directly into homes. So, next time you see one, think of the mail it once delivered, connecting the past to the present.
