This video is of a re-enaction of a Danish gun defending Fredericia against Schleswig-Holsteiner attack in 1849. Now only firing blanks towards cars.
Russians vainly attack Narva Castle during a re-enaction of the winter Charles XII's Swedish victory 310 years after the event in 1700. Five years later in 1705 Peter the Great's Russian victory in the summer (which is also re-enacted), saw Narva made part of the Russian Empire for nearly all of 300 years. Narva is now an Estonian and European Union border town with 80% of its population Russian speaking.
