Saturday, August 15 is one of Poland’s most significant public holidays — a rare double occasion combining Assumption of the Virgin Mary (a Catholic feast day) and Armed Forces Day (Święto Wojska Polskiego), marking the anniversary of the 1920 Battle of Warsaw. For visitors in Poland this weekend, there are several things worth knowing in advance.
What Closes on August 15
Under Polish Sunday trading law, August 15 is treated as a restricted trading Sunday even though it falls on a Saturday this year. This means:
- Most supermarkets, retail chains, and shopping centres are closed or operating on reduced hours
- Banks and post offices are closed
- Government offices and public services are closed
- Pharmacies on duty will be open (one per district on a rotating basis — check the sign on your nearest pharmacy for the duty address)
Restaurants, cafes, and tourist attractions remain open and often see strong trade. Museums in Warsaw and Krakow will be operating on normal summer hours.
Warsaw: Military Parade and Road Closures
Warsaw hosts the national Armed Forces Day military parade on August 15 along Aleje Jerozolimskie, the main east-west artery through the city centre. The parade typically runs from approximately 10:00–13:00, during which significant road closures affect central Warsaw, including the area around Rondo Dmowskiego and the bridge crossings. Public transport routes in the centre will be diverted.
If you are visiting Warsaw on August 15, factor in the parade zone when planning your morning. The National Stadium on the east bank is a recommended viewing point with good transport links from Praga.
Częstochowa: Pilgrimage Crowds
August 15 is the culmination of the annual Black Madonna Pilgrimage to Jasna Góra Monastery in Częstochowa. Over 150,000 pilgrims arrive on foot from Warsaw, Krakow, and other Polish cities, many having walked for several days. The railway station and roads in Częstochowa will be very congested on August 13–16. Factor this in if Częstochowa is on your itinerary.
Krakow: August 15 as a Good Visit Day
In Krakow the holiday is observed more quietly. The Main Market Square holds an informal outdoor celebration in the afternoon, and many restaurants offer festive menus. With most residents leaving the city for the long weekend, Wawel Castle, the Cloth Hall, and Old Town streets can feel less crowded than a typical August Saturday. Advance booking for popular restaurants is still recommended.
