Scientific discoveries made with the aid of Iceland spar from Iceland directly influenced the development of modern society. Progress since its discovery in the 17th century until 1930 in various important fields of the natural sciences and technology, would have been delayed by decades if Iceland spar had not been available at that time. As the sole supplier of first-class spar crystals for scientific purposes Helgustaðir in Reyðarfjörður may therefore be considered the most valuable location in Iceland in an international context.
The project contains:
1. Exhibition put up at Breiðdalssetur in Breiðdalsvík this sumar, then later to be moved to Eskifjörður
