In 1953, the general store and post office of Ochopee, Florida burned down. So local residents converted an irrigation pipe shed on a tomato farm into a temporary post office. It stayed there and remains in business to this day.
It serves residents of 3 counties and was once a bus stop. A single Postal Service employee works there, sorting mail into slots on the back wall. In addition to being a functional service point, the Ochopee Post Office is also a popular tourist attraction as it is the smallest Post Office in the United States.
This is 1 of 7 of America's smallest civic institutions rounded up by Atlas Obscura, including the smallest national forest (33 trees) and a police station the size of a phone booth.
