Recurrent event or a village
Maybe an even that would last 4-5 days and reoccured every year. Like Öland has its Skördefest, Boom its Tomorrowland :) etc. Or some kind of recreation of a battle or so that people could take part in? With old wooden ships taking people up and down the fjord or into the sea? A small village you can stay in and enjoy the life of the old times? People trying their luck building a boat, cutting down a tree etc...
A few ideas...
