Porsmyr Bygdetun is a old farm witch consists of the main house, a large outhouse and two traditional storehouses.
The property is located 200 metres south of Greipstad Church in Nodeland.
Songdalen Municipality bought the property in 1997 for it to be used as a rural museum and it is managed by the foundation called Porsmyr. Restoration is well under way as a result of voluntary work by Porsmyrs Venner / Porsmyr's Friends. They have also found and restored the first fire engine in Songdalen, in addition to three old tractors.
