Osebro is the best preserved part of Porsgrunn town.
Until our time it was the shipping and trade that characterized the district. Trade flourishes still, and the river is becoming a major traffic artery for large and small vessels.
A walk through Osebro district and Osebakken takes you to a pleasant environment, historical buildings and interesting shops.
It has been the site of commerce and business for many centuries and includes one of Porsgrunns oldest residential areas.
