Frequently asked questions
What exactly is Rynek Underground?
It's a large museum built four metres beneath Kraków's Main Market Square, over the real excavated remains of the medieval city. You walk on glass floors above the archaeology while holograms, projections and reconstructed market stalls recreate Kraków as it was seven hundred years ago. The entrance is inside the Cloth Hall (Sukiennice) in the middle of the square.
Do I need to book a specific time?
Yes. Entry is timed and daily numbers are capped, so you choose a date and entry slot when you book and your ticket is valid for that slot. It's one of Kraków's most popular museums and peak dates sell out days to a week or more ahead — booking in advance is the difference between visiting and not.
How long does the visit take?
About 75 minutes. The exhibition is immersive and detailed, and it's all underground — which also makes it a perfect choice for a rainy or cold day in Kraków.
Where is the entrance?
Inside the Cloth Hall (Sukiennice), the long market building in the centre of the Main Market Square — look for the museum entrance on the northeastern side. It's a few minutes' walk from anywhere in the Old Town, so it's very easy to reach, but easy to walk past if you don't know to look for it.
Is it suitable for children?
Very much so — the holograms, glass floors and reconstructed medieval market tend to captivate children and adults alike. The family ticket covers up to four people.
Can I just turn up and buy a ticket at the door?
Sometimes, but it's a gamble — on-the-door tickets depend on unsold timed slots, and at peak times the day is gone by early afternoon. A reserved timed slot removes both the queue and the risk.
What about the free admission day I've read about?
The museum offers free entry on Tuesdays, but those tickets are issued only in person at the box office on the day, in limited numbers (five per person). If your Kraków time is short, a guaranteed timed slot on another day is usually the better trade. We don't sell the free tickets — we'll always tell you honestly when free admission is the smarter option.
What happens after I book?
You receive confirmation with your dated, timed ticket and plain-English notes on finding the Cloth Hall entrance and what to expect below. Everything is digital — show it on your phone at the door. There's a real person on our side if anything changes.
Are you the museum, or an official reseller?
Neither — we're an independent concierge service for international visitors. We facilitate genuine official timed-entry tickets and add booking and support in your own language; our service fee is included in the price shown. If you'd rather book directly, the operator's site is bilety.mhk.pl.
