Risør Underwater Post Office

The Risør Underwater Post Office operates in a fiberglass diving bell structure filled with air, secured by a 5-ton weight at 4 meters depth.

Established in 2004 by a local SCUBA diving club, the facility faced closure in 2011 but continued operations after intervention from the tourism board.

The Norwegian Postal System authorized this dry underwater post office, making it a distinctive example of maritime postal infrastructure in southern Norway.

Visitors deposit mail in a post box near the pier, which the postmaster collects multiple times weekly using waterproof containers during summer months.

Letters processed at this location receive special cancellation marks with underwater motifs, distinguishing them from regular postal correspondence.
