Rynek Underground

Rynek Underground (Podziemia Rynku) is a museum built into the excavated foundations of the medieval market, about four metres below the paving of Rynek Glowny. It opened in 2010 as a branch of the Museum of Krakow, covering roughly 4,000 square metres under the eastern half of the square. You walk the original cobbled paths of the old marketplace on glass floors, past the stone footings of stalls and workshops that traders used more than six hundred years ago.

This is the clearest picture you will get of how medieval Krakow actually worked. The route mixes real archaeology with holograms, touchscreens and projections, so it holds the attention of children as well as history readers. It is fully indoors and climate-controlled, which makes it one of the better options in the centre on a wet or very hot day. Entry is timed and numbers are capped, so it rarely feels crowded once you are inside.

The exhibition is built around what the digs uncovered between 2005 and 2010: the foundations of 13th and 14th century trading stalls, remains of workshops, sections of the old market surface, and everyday objects such as coins, tools, jewellery and lead seals used in the cloth trade. Reconstructed scenes and scale models show the square as a working hub of European commerce, when Krakow sat on trade routes linking north and south. Multimedia stations let you follow the story of the city's growth, its guilds and its links to the wider Hanseatic and Mediterranean networks. Give yourself time for the screens rather than rushing the walkways.

Most visitors spend between one hour and ninety minutes here. If you want to read the panels and watch the films properly, plan on the longer end. It pairs naturally with the Cloth Hall gallery and St Mary's just above, so you can build a half day around the square without walking far.

Because entry is by timed slot and capacity is limited, summer slots sell out, so book online a day or two ahead in July and August. Early morning and the last entries of the day tend to be quietest. Check the museum's official channels for current opening days, as branches of the Museum of Krakow close on set days of the week and the underground closes for occasional maintenance.

The entrance sits on the Main Square, on the side of the Cloth Hall, in the centre of the Old Town. From Krakow Glowny station it is about a ten-minute walk south through the Planty gardens. The whole centre is pedestrianised, so the nearest trams and buses stop around the edge of the Old Town. For getting around the rest of the city, see the Krakow guide.

The museum lies below ground and is reached by stairs and a lift. The route runs across glass floors and uneven historic surfaces in places, and the lighting is deliberately low. If you have specific access needs, contact the museum before your visit to confirm the current arrangements for the lift and the walking route.

You are in the middle of the Old Town, so everything central is close:

• The Main Market Square and St Mary's Basilica, directly above.
• The Cloth Hall and its gallery of 19th-century Polish painting, in the same building.
• The Czartoryski Museum, a few minutes north near the Florian Gate, home to Leonardo's Lady with an Ermine.

It is an archaeology museum set on the excavated remains of the medieval market, about four metres below the Main Square. It opened in 2010 and is run as a branch of the Museum of Krakow.

In summer, yes. Entry is by timed slot with a cap on numbers, and slots often sell out on busy days. Outside peak season you can usually buy on arrival, but booking online avoids the queue.

Yes. The holograms, models and touchscreens are aimed at keeping younger visitors engaged, and the walk is short. The low lighting can feel dim for very small children, so keep them close on the glass floors.
