On the 6th of June, 2004 the post historical exhibition in the post building opened in the urban environment at Maihaugen. Visitors interested in postal history can follow Norway Post's approximately 370 years of history as an important player in Norwegian society and industry. During the summer season, the post building is serviced by a Postmaster. The rest of the year the exhibition is open on request. Maihaugen and the Norwegian Postal Museum have their own postmark, making it possible to send a letter or postcard from here.
The Norwegian Postal Museum at Maihaugen has a library, a collection of objects, a collection of uniforms and a photo archive. Part of the object and photo collection is available for searches on the internet, see Digital Museum.
