The town of Narrowhaven was the main settlement of the Lone Islands on the Island of Doorn, and was the seat of the Islands' government. The castle of Narrowhaven was first the seat of the governors of the Lone Islands, and later of the Dukes.
In the Voyage of the Dawn Treader film, Narrowhaven was also the place where people were sent out onto the sea, as sacrifices to the Green Mist. Bern was their prisoner for many years, though why he wasn't sacrificed is unknown, until the crew of the Dawn Treader freed the people from the slaver's reign during the Battle of Narrowhaven.
