Syttende Mai (17th of May) is celebrated on May 17th every year. In 2027, Norway's Constitution Day falls on May 17th. The day commemorates the signing of the Norwegian Constitution in 1814 and is celebrated with colorful children's parades (barnetog), traditional folk costumes (bunad), and festive gatherings throughout Oslo.
Families love watching the children's parade (barnetog) wave Norwegian flags and march through the city. Traditional activities include outdoor games, eating hot dogs and ice cream, participating in community celebrations, and dressing in bunad (folk costume). Many parks in Oslo host family concerts and activities on Constitution Day.
A bunad is a traditional Norwegian folk costume, worn proudly on Syttende Mai. Each region of Norway has its own distinct bunad design with elaborate embroidery. You'll see many Norwegians in Oslo wearing their regional bunad throughout the day. It's a symbol of Norwegian cultural heritage and national pride.
Traditional Syttende Mai food is simple and festive: hot dogs (pølse), ice cream, waffles with jam and sour cream, and strawberries. Many families enjoy outdoor picnics and gatherings. Look for outdoor stalls and festive food vendors in Oslo on the day.
