It might be odd to imagine a herd of Danish folks running around waving American Flags and singing “The Star-Spangled Banner,” but if you ever have the desire to fly to the country’s northern Rebild region in early July, you could witness the phenomenon for yourself. Vice notes you’re even likely to catch an air show with swooping fighter jets, children running around in face paint, Danish American celebrities, and a seemingly bizarre intermingling of Danish and American foods and music. But the celebration is more than just hotdogs and pickled herring.

According to BBC, Denmark has held the largest foreign American Independence Day celebration every year at Rebild National Park for over a century, and there’s a legal reason for this. The park was purchased by a group of a Danish Americans in 1911. The following year, it was deeded to the country of Denmark under the conditions that the land would remain a permanent, undeveloped memorial to Danish American heritage. Since then, it’s been a space where those of this specific cultural mix can gather to celebrate United States holidays, of which Rebildfesten (the Fourth of July) is the most popular.

Unlike the single-day celebration in the United States, the Danes do it right, holding a four-day party attended by thousands of Danes, Americans, Danish Americans, and tourists. Seeing the mix break it down to both countries’ folk songs while slapping back schnapps and American beer is truly a sight to behold.
