It’s a small museum and you will enjoy it if you still get very excited while sending/receiving mail by regular post don’t forget to write your letter!
Very nice exhibitions on postal history and stamps.
Barnvänligt!
Not quite as interesting as I’d hoped Wouldn’t bother visiting unless you’ve got kids or are REALLY interested in the history of the Swedish postal service.
You can see the entire history of Swedish postal services here, along with a little post office, a fun place for kids.
