What Is Constitution Day and Why Oslo?
The 17th of May marks the signing of the Norwegian Constitution at Eidsvoll in 1814. It is a full national public holiday and, unlike many countries' national days, it is explicitly civilian and child-centered rather than military. Oslo draws the largest celebrations in the country, partly because the Royal Family appears on the balcony of the Royal Palace to greet the parade, and partly because the capital concentrates the country's biggest schools, marching bands, and civic organizations.
For visitors, Norway in May offers something genuinely difficult to replicate elsewhere: a spontaneous-feeling street festival where over 100,000 people dressed in national costume (bunad) fill the streets, children wave flags, and the mood is celebratory rather than solemn. It is worth planning specifically around, but only if you understand the logistics. The standard Oslo itinerary simply does not apply on this day.
ℹ️ Good to know
17 May is NOT primarily a military parade. The centerpiece in Oslo is the barnetoget, a children's parade with school classes and marching bands. Military ceremonies exist elsewhere in the country, but central Oslo belongs to the kids and their families.
The Programme: What Happens and When
The day starts early. A morning chorale and memorial services take place around 07:00, and a cannon salute with the Liberty Bell ringing at Akershus Fortress happens at 12:00. These are worth attending if you want a quieter, more reflective moment before the main parade crowds arrive.
The children's parade (barnetoget) is the centrepiece. It begins at the main gate of Akershus Fortress and moves up Karl Johans gate toward the Royal Palace, where the Royal Family greets the marchers from the palace balcony. The parade runs approximately 10:00 to 13:30, though the exact timing varies by school group and year. The official programme is published annually by Oslo Kommune and updated each spring, so check their site for the current year's schedule.
- 07:00 Morning chorale and memorial services begin. Quieter, atmospheric, recommended for early risers.
- 10:00 Children's parade (barnetoget) starts from the main gate of Akershus Fortress.
- 12:00 Cannon salute and Liberty Bell ringing at Akershus Fortress.
- 10:00–13:30 Parade moves up Karl Johans gate; Royal Family appears on the Royal Palace balcony.
- 13:30 onward Streets reopen gradually; afternoon celebrations continue in parks and private homes.
Around tens of thousands of children and marching bands participate in the Oslo parade alone. The route along Karl Johans gate is lined several rows deep, and the area directly in front of the Royal Palace fills up very early. If you want a good spot there, arrive before 09:00. Ticketed tribune seats along sections of the parade route are sold in advance through VisitOSLO's 17 May page, and they sell out weeks beforehand.
Navigating the Crowds: Where to Watch and Where to Avoid
The area around the Royal Palace and the top section of Karl Johans gate becomes extremely congested from around 09:30. Some viewing areas have controlled entry, and certain entrances close at 10:00 once they reach capacity. Crucially, once you are inside a controlled viewing zone, you may not be able to leave until the parade ends around 13:30. Factor this in if you have other plans.
A less crowded option is to watch the parade at the lower section of Karl Johans gate, closer to the Akershus Fortress starting point. The atmosphere is still electric, and you have much more freedom of movement. Central Oslo is essentially car-free for the entire day, so walking between viewing spots is straightforward if you plan your route before the parade locks down the main streets.
⚠️ What to skip
City centre streets are closed to car traffic for most of the day. Do not attempt to drive to or park near the Royal Palace, Karl Johans gate, or Aker Brygge. The closures are enforced, and you will lose significant time. Walk or take public transport.
- Arrive at the Royal Palace viewing area before 09:00 for a front-row spot.
- Mid-Karl Johans gate offers a good balance: good sightlines, easier exit.
- Akershus Fortress area: good for the early 07:00 ceremonies and the 12:00 salute.
- Frogner Park (Vigeland) hosts local neighbourhood celebrations after the main parade, quieter and family-friendly.
- Avoid Nationaltheatret station entirely on parade day; it becomes chaotic.
Public Transport on 17 May: What Changes
This is where most visitors get caught out. Public transport in Oslo on Constitution Day is significantly altered, and assuming normal service will leave you stranded or late.
The metro (T-bane) generally runs with reduced frequencies similar to a weekend schedule, and the key advice from Ruter is to use Stortinget or Jernbanetorget stations for access to the city centre. Nationaltheatret metro station becomes extremely congested and Ruter specifically advises against using it.
Trams are diverted between 08:00 and 17:00. The stops at Nationaltheatret, Øvre Slottsgate, Dronningens gate, and Stortorvet are all closed. If your hotel is near any of these stops, plan your walking routes in advance. Many buses also run with detours and some departures are cancelled in the 08:00 to 17:00 window.
✨ Pro tip
Check Ruter's journey planner (ruter.no) the day before and the morning of 17 May. They publish specific 17 May route maps and PDF timetables each year. The best strategy for most visitors is to walk to and from the parade route rather than relying on trams or buses in the centre.
What's Open, What's Closed
17 May is a full public holiday. Most offices and regular-sized shops are closed, and many larger supermarkets also close or operate on very limited hours. Do not plan a shopping trip, and do not count on grabbing groceries. The exception is hospitality: cafes, bars, and restaurants generally remain open, and many do strong business on the day. Some run out of seating entirely by late morning, so eat breakfast early or book ahead.
The Oslo Visitor Centre is typically open on 17 May with reduced hours (around 09:00 to 14:00), which is useful if you need maps or last-minute information. Museums have variable policies: some close entirely, others open on reduced hours. If you are planning to visit the Fram Museum or the Norwegian Folk Museum on Bygdøy, check their individual websites well in advance, as 17 May hours differ from standard schedules.
- Closed Most shops, supermarkets, and government offices. Plan food and supplies the day before.
- Open Most cafes, bars, and restaurants, though very busy. Book a table if you want a sit-down meal.
- Open (limited) Oslo Visitor Centre, 09:00–14:00.
- Variable Museums and attractions. Check each venue's website for their specific 17 May hours.
- Open as normal Pharmacies (apotek) on rotating duty hours; check which is open nearest to you.
Practical Advice for Visitors: Weather, Dress, and Logistics
Norway in May sits solidly in spring, but Oslo's weather on the 17th can range from crisp sunshine to grey skies and light rain. Average temperatures are around 11–14°C, with occasional colder days. Locals wear their bunad (national costume) regardless of weather, sometimes over thermal layers. Visitors should dress in adaptable layers: a waterproof outer layer is strongly recommended. The celebrations continue outdoors no matter what the sky does.
Oslo's city centre is extremely walkable on 17 May precisely because cars are excluded. The walk from the Opera House near Bjørvika to the Royal Palace along Karl Johans gate is about 1.5 km and passes through the heart of the celebrations. Comfortable walking shoes are essential; you will be on your feet for several hours. If you are visiting Oslo with children, 17 May is one of the best possible days to do it, as the entire event is child-centered and the atmosphere is genuinely joyful rather than rowdy.
Accommodation books up faster for 17 May than almost any other date in Oslo's calendar. If your dates are flexible, book several months in advance. Prices rise noticeably around the holiday. The weekend around 17 May is also a peak period, so even arriving a day or two before the date means competing with domestic Norwegian travellers coming to Oslo for the celebrations.
💡 Local tip
Bring a small amount of cash or make sure your card works contactlessly. Street food vendors, ice cream carts, and small drink stalls proliferate on the day, and although many accept cards, some may not. Carry NOK 100–200 in small notes for snacks and spontaneous purchases if you want a backup option.
FAQ
Is 17 May worth visiting Oslo for if you are not Norwegian?
Yes, genuinely. The barnetoget is one of the most photogenic and warmly atmospheric public events in Scandinavia. Visitors are welcome everywhere along the route, and Norwegians are typically happy to explain the traditions. The main drawback is that most shops are closed and transport is disrupted, so you need to plan around the event rather than treat it as a background to normal sightseeing.
Can I get close to the Royal Palace balcony to see the Royal Family?
Yes, but you need to arrive early. The area in front of the Royal Palace fills up from about 09:00. Some viewing sections have controlled entry that closes at 10:00. If you are inside a controlled zone, you may not be able to leave until after 13:30 when the parade ends, so bear that in mind before committing to a spot.
How do I get around Oslo on 17 May without a car?
Walking is the most reliable option in the centre. The metro runs on a Saturday schedule (roughly every 15 minutes) and is generally fine; use Stortinget or Jernbanetorget stations and avoid Nationaltheatret. Trams are diverted between 08:00 and 17:00, and several central stops are closed. Check Ruter's journey planner and their specific 17 May route maps before you travel.
What are the best restaurants or cafes to visit on 17 May in Oslo?
Most cafes and restaurants are open and busy. Areas like Aker Brygge, Grünerløkka, and the streets around Youngstorget have a high concentration of places. Booking ahead is strongly advised for sit-down meals, especially for lunch between 12:00 and 14:00 when the parade ends and thousands of people are suddenly hungry at the same time.
Is 17 May just in Oslo, or do other Norwegian cities celebrate too?
Every town and city in Norway celebrates Constitution Day with its own parade and events. Oslo is simply the largest and most famous celebration because of the Royal Family's appearance on the palace balcony. If you prefer a quieter but still authentic experience, smaller cities and coastal towns hold their own barnetoget with a much more local, low-key feel.
