There are Six world heritage sites in Finland at the moment, heres the list, Suomenlinna, Old Rauma, Bronze Age Burial Site of SammallahdenmÃ¤ki,PetÃ¤jÃ¤vesi Old Church,Verla Groundwood and Board Mill, and Struve Geodetic Arc.
I found out by accident that I’d visited two already, Rauma and Suomenlinna, & they don’t differ from most of the others on the list worldwide, they are worthy buildings or places of natural beauty. But one howevever is a little different. The Struve Geodetic arc which I didn’t know anything about before I found it on this list. It is maybe the biggest thing on the world heritage list but contains no area of outstanding beauty or special built monument. It is a collection of coordinates for mapping the Earth before GPS. What is so remarkable is that so many countries have participated in it, it runs from Norway to the Black sea (I think it added to down to South Africa but I’m not sure) and at a time before these international efforts are thought of as having happened. Its the remains of an outdated method for calculating the earths circumference and has become mapping history but is important because of the idea and ideals it imbodies which allow us today through GPS and Google maps to use this information in more and more useful ways & Struve was the originator of this collective effort.
040406 update: I found this page from the Finnish National Board of Antiquaties which gives a good rundown of the six sites should you want more info.
