Best Warsaw museums for May long weekend 2026 - family guide
The Polish “majowka” of 2026 falls on a single long weekend: Friday May 1 (Labour Day, public holiday), Saturday May 2 (National Flag Day of Poland), and Sunday May 3 (Constitution Day, public holiday). Three days in a row, bookended by two public holidays - perfect for extended sightseeing in the capital. Below is a practical guide to Warsaw’s museums for the May long weekend.
Dates: Friday May 1 - Sunday May 3, 2026.
A note on hours: some museums apply special holiday hours on May 1 and May 3. This guide reflects regular schedules; before travelling, verify holiday hours on each museum’s official website, especially for May 1.
Three-day quick plan
| Day | Character | Good picks |
|---|---|---|
| Friday May 1 | Labour Day - many state institutions closed | Independent museums, CNK, POLIN, National Museum |
| Saturday May 2 | Flag Day - regular working day for museums | All museums on regular schedules |
| Sunday May 3 | Constitution Day - open, often with themed programming | Royal Castle, Museum of Warsaw, thematic exhibitions |
Friday May 1 - Labour Day
Confirmed
The Royal Castle is closed on May 1. The Castle does not admit visitors on Labour Day. New prices and hours take effect from May 2 - buy your ticket for Saturday or Sunday instead.
Open on Labour Day
The following museums typically operate on May 1 with hours close to regular (always worth confirming):
National Museum in Warsaw Al. Jerozolimskie 3, Śródmieście | mnw.art.pl
Regular Friday hours: 10:00-20:00 (extended). Over 830,000 works in the collection - Faras Gallery, Matejko, Cranach, 20th-century art.
POLIN Museum of the History of Polish Jews ul. Anielewicza 6, Muranów | polin.pl
Regular Friday hours: 10:00-18:00. Monday closed, Tuesday closed - Friday is a good day. 1000 years of Polish Jewish history, interactive core exhibition.
Copernicus Science Centre (CNK) ul. Wybrzeże Kościuszkowskie 20, Powiśle | kopernik.org.pl
Regular Friday hours: 09:00-20:00. 450+ interactive exhibits, Planetarium. On days off and holidays queues can reach two hours - arrive early.
Warsaw Rising Museum ul. Grzybowska 79, Wola | 1944.pl
Regular Friday hours: 8:00-18:00. Over 3000 m2 of exhibition space, 3D film “City of Ruins”. Heavy tourist traffic during the long weekend.
Outdoor backup
If your first-choice institution is closed May 1, consider Royal Lazienki Park - the park is open daily 6:00-21:00 and Lazienki is a natural fallback for a long weekend. Spring in full bloom, roses beginning to open, Chopin concerts in season.
Saturday May 2 - Flag Day
Flag Day is not a statutory day off, so museums run on regular Saturday hours. This is the most “normal” day of the May weekend.
New Royal Castle prices take effect from May 2 - check zamek-krolewski.pl on the day of your visit.
Good day for:
- Royal Castle - first day after Labour Day with new hours and prices. Recommended: “The Grand Game. Władysław IV’s Opera” (new exhibition from April 17 through summer).
- National Museum - Saturday hours 10:00-18:00. Good time for Matejko’s “Battle of Grunwald” and Faras Gallery.
- Royal Lazienki Museum - Saturday is a standard park day, easy to combine with a short walk in the Royal Gardens.
Sunday May 3 - Constitution Day
The Constitution Day holiday has strong tradition in Warsaw. Many museums open, some with themed programming. The Royal Castle is open on May 3 - this is one of Polish history’s most important dates and the Castle holds ceremonies and temporary exhibitions tied to the Constitution.
Worth planning:
- Royal Castle - the Constitution of May 3, 1791 was passed in part in the Castle’s Chambers of the Sejm. Temporary exhibitions: “The Last Castle. Polish Castle Heritage” (through June 28), “For Love. Objects for the Fashionable and Those in Love” (through May 17). Expect higher attendance.
- National Museum - regular Sunday hours 10:00-18:00, a chance to engage with Matejko’s history on a national holiday.
- Warsaw Rising Museum - the patriotic tone fits Constitution Sunday.
Families with children - what to choose for May weekend
Kid-focused ranking:
- Copernicus Science Centre (CNK) (age 4+) - winner of every ranking, interactive exhibits, Planetarium. On days off arrive before 11:00 - queues build up later.
- Museum of Warsaw (age 6+) on the Old Town Market Square - atmospheric location, accessible exhibition.
- Wilanow Palace (age 5+) - baroque royal residence + gardens, May spring in full bloom. Museum + park combo.
- Royal Lazienki - park is free, open daily 6:00-21:00, pavilions (Palace on the Isle, White House, Old Orangery) on variable hours.
Lazienki + Wilanow combo: both are palatial spring gardens; doable in one day but requires a bus (lines 116, 180, 519 to Wilanow).
Special May-weekend events 2026
“Coming of Age” - exhibition opening at Zachęta on May 1. Zachęta - National Gallery of Art opens a major new exhibition “Dojrzewanie” (Coming of Age) on Friday May 1, 2026. The show runs through September 20 - but the vernissage and opening days over May weekend are a chance to catch a fresh cross-section of Polish contemporary art. Zachęta is at pl. Małachowskiego 3, Śródmieście, next to Piłsudski Square.
“The Grand Game. Władysław IV’s Opera” - Royal Castle. A major new exhibition on baroque royal opera, open from April 17 through July 19. May weekend is the first long weekend on which the exhibition is open to the broader public.
“Spring Awakening” - National Museum. Ceramics from the Old Masters Gallery, exhibition running through May 4. The May weekend is the last chance.
Practical tips
Queues and crowds. The May weekend is peak tourist season in Warsaw. At CNK, the Royal Castle, POLIN and the Warsaw Rising Museum expect queues - especially on May 1 (many Polish residents off work) and May 3 (Constitution holiday). Reserve tickets online in advance for these museums.
Free days. Check your museum’s regular free day:
- POLIN: Thursdays (in May weekend: only Thursday April 30 is usable before the weekend)
- Royal Castle: Wednesdays
- National Museum: Tuesdays (permanent galleries)
More in the free museums guide.
Weather. Early May in Warsaw can be cool but often sunny. Have a plan B for rain - the indoor museum list above.
Transport. Krakowskie Przedmieście, Nowy Świat and the Royal Route typically have traffic restrictions on May 3 for state ceremonies. Plan tram (lines 1, 4, 15, 18, 35) rather than car that day. Many museums (Royal Castle, National Museum, Warsaw Rising) are reachable from the metro with a short walk.
Food. The National Museum, Royal Castle, CNK and POLIN have in-house cafes. For a planned lunch - the Old Town or Krakowskie Przedmieście.
What not to expect
- May 1: some smaller private museums and state galleries may be closed without advance notice. Call or check the site on the day.
- Parking in the centre: especially Krakowskie Przedmieście on May 3 - may be fully closed to traffic.
- Full opening hours: some museums shorten hours on holidays (closing at 16:00 instead of 18:00). Shortened hours are not always published well in advance - verify.
