If you only have a few hours during a long weekend in Kraków, stop by St. Wojciech's Church — not for its size, but for its history and the underground exhibition. This is one of the oldest sacred sites in the city, and its Romanesque fragments are a literal witness to the beginnings of Kraków. A visit here won't take long, but it will add depth and context to your trip.
The church stands in the southeast corner of the Main Market Square (address: Rynek Główny 2) and immediately catches the eye with its stone, Romanesque form — although the present appearance owes much to later Baroque alterations. The most interesting things, however, are hidden beneath the floor: the crypt and archaeological reserve reveal layers of the city from centuries past.
If you're sightseeing with limited time — step inside, check whether the underground exhibition is open (seasonal), and treat this stop as a quick glimpse into a thousand years of Kraków's history.
The interior is small and mainly Baroque-Rococo in style, with a few valuable artifacts, including a crucifix from the early 15th century and a painting of St. Wojciech from the early 17th century. Look for details — angels and 18th-century sculptures and preserved Romanesque stonework near the entrance.
The biggest attraction is the underground: exposed fragments of Romanesque walls and remnants of earlier wooden structures show how the level and use of the Market Square changed over time. You can also see burial sites and archaeological layers that document urban life across centuries. The basements give a clear impression that the Market Square pavement now sits nearly 2 metres above the church's original level.
With the small exhibition you can follow urban and religious changes in this part of the city in a matter of tens of minutes — a great complement to a walk around the Market Square.
Tradition links the site with the missionary activity of St. Wojciech (Adalbert) and his journey north; the first wooden sacred centre likely appeared here around the 10th–11th centuries. The stone Romanesque church was constructed at the end of the 11th or beginning of the 12th century and was modernised and expanded in later centuries, especially in the 17th–18th centuries, which added Baroque elements.
Archaeological research has revealed numerous burials (hundreds of remains) and fragments of earlier structures — proof of the site's centuries-long role as a social and religious centre. Today the church is one of the oldest preserved elements within the Main Market Square area.
The underground exhibition is usually open seasonally — it's best to check before you arrive whether the display is accessible. In summer the basements and historical exhibition are often open daily except Sunday; at other times the museum may publish specific days and hours (last entry commonly half an hour before closing).
Visiting the underground is a short but information-rich experience — tickets are modest (a few zlotys for a regular ticket, cheaper for concessions). In some periods there are free-entry days, for example on certain weekdays — check current announcements.
If you come for a long weekend, plan your visit for the morning or early afternoon to avoid the biggest crowds on the Market Square. Remember the church is small — access to the interior may be limited during Mass, so factor this into your schedule.
If you have one day or a long weekend in Kraków, consider a simple plan: walk the Main Market Square (Cloth Hall, St. Mary’s Church) – take a coffee break – a short visit to St. Wojciech's Church with a descent to the underground (if the exhibition is open) – then walk toward Wawel or Kazimierz. This gives you a contrast between the "big" history represented by the cathedral and Wawel, and the more intimate — but foundational — site that is St. Wojciech's.
It’s an excellent stop for visitors who like condensed history — you’ll soak up the Market's atmosphere while seeing the archaeological "core" layers of Kraków.
Around the Market you’ll find both traditional Polish restaurants and cosy cafés or bakeries perfect for a quick break. If you want tried-and-true places, consider cafés such as Café Camelot on Św. Tomasza for good coffee, and for an elegant meal you can choose a restaurant with a Market view. Keep in mind that the dining scene changes, so checking recent reviews before you go is a good idea.
If you plan to stay over a long weekend, book in advance. Boutique hotels by the Market and in the nearby streets let you make the most of a short visit — staying close saves time on transport.
St. Wojciech’s Church literally sits below today's Market pavement — the Romanesque walls you see are nearly 2 metres under the current level. It’s a clear example of how the city’s surface rises over centuries.
Hundreds of burials were discovered in the basements — an unexpected sign that the place functioned as a necropolis for many centuries. For history lovers it’s a mini archaeological museum in the heart of the Market.
Few people know the underground displays are sometimes updated — there are thematic exhibitions, comic-book publications for children, or catalogues illustrating recent research. That means it’s worth returning on another visit.
Assuming the church is always open for visitors — remember access to the underground is seasonal and the interior can be partially closed during services. Always check current opening times.
Thinking it's a "major" attraction — the church is small; don't plan to spend a long time here. Treat it as a complement to your Market walk.
Ignoring museum rules in the basements — this is a museum space: keep quiet, don’t touch exhibits and check the photography rules.
Is it worth going inside for 15–30 minutes? Yes — in a short time you can see Romanesque fragments and feel the place’s history.
Are the undergrounds always open? No — the exhibition is seasonal. It is more often available in the warm season (spring/summer); outside the season it may be closed. Check exhibition information before you arrive.
How much time should I reserve? 20–45 minutes is enough for the interior and a quick visit to the underground if the exhibition is open.
Is there an entry fee? Entry to the underground is usually ticketed — prices are modest. There are sometimes free-entry days (for example, certain weekdays in season) — check current news.
If you want to make the most of a long weekend in Kraków, treat St. Wojciech's Church as a "short lesson" about the origins of the urban space. Go inside, go down to the underground if open, then sit for a coffee and watch Market life.
