Lyngør is famous for being acclaimed "Europe's best preserved village" by Europa Nostra in 1991, and also for a dramatic sea battle between English and Danish/Norwegian forces during the Napoleonic wars resulting in the sinking of last great battleship of the Danish/Norwegian forces, Najaden by the large British ship Dictator in 1812.

Around 1600 Tvedestrand was mainly a beach for the Berge and Tveite farms's boats, herby the name Tvedestrand (strand means beach in Norwegian). The town as we now know was built in the 19'th century as a harbour for Norways longest existing iron works, Næs jernverk.
