Grenland and the Skien fjord are flatter regions located closer to or at the coast. Historically Grenland referred to what is now called Midt-Telemark, but over time the name Grenland has come to refer to the Skien fjord area. The latter is traditionally characterized by its cities and its involvement in seafaring and trade. It also includes several larger agricultural properties and estates, as well as industry. The culture and social structure are more urban, far less traditional, more influenced by contact with continental Europe and far less egalitarian. The most important city of the region, Skien, was historically one of Norway's most important cities, although its importance declined after the Napoleonic Wars. The playwright Henrik Ibsen was a native of Skien, and many of his plays are set in places reminiscent of the city and area.
