The European Fortress Day Concept (2019)


For centuries, fortifications have been used to fend off enemies. Today, our fortress heritage is used to welcome the public in a peaceful manner. European Fortress Day is the best way to show our Europe-wide diversity to its citizens.

Europe is a patchwork of cultural diversity, and we are connecting the dots: together and all over Europe celebrating the second European Fortress Day.

This event coincides with the European Heritage Days,  therefore the European Fortress Day can take place on different dates in different countries.

Send us your photos and let us know how you have experienced European Fortress Day.
