Rynek Underground Museum in Kraków: Tickets, Hours and What to Expect

The Rynek Underground (Rynek Podziemny) is an archaeological museum built a few metres beneath the eastern half of Kraków's Main Market Square, with its entrance on the eastern side of the Cloth Hall, facing St Mary's. A normal ticket costs 45 PLN, entry is free on Tuesdays, and every ticket carries a fixed entry time. The museum's own visiting rules warn that turning up without a booking may mean you do not get in.

The short answer. Book a timed ticket online a few days ahead, allow at least an hour underground, and skip the free Tuesday unless you are happy to queue at the box office early. Prices and hours below come from the Museum of Kraków's own pages and were checked in September 2026.

What the Rynek Underground actually is

Between 2005 and 2010 archaeologists dug up the eastern side of the square, the part between the Cloth Hall and St Mary's Basilica. Instead of filling the hole back in, the city built a museum around what they found. The result is an archaeological reserve of nearly 4,000 square metres, a few metres below today's paving, with a walkway running through the cellars of the old trading stalls. The Museum of Kraków opened it on 24 September 2010 under the name "Following the traces of European identity of Kraków".

The name tells you the angle. This is not a display of pretty objects in glass cases. It is the story of how a square laid out in 1257 grew into one of the largest medieval marketplaces in Europe. It is also the story of what was here before it: a cemetery from the 10th century, then a settlement of craftsmen that the Mongol invasion of 1241 wiped out. You walk on the ground those people walked on, and the square is directly above your head.

Tickets and prices in 2026

The Museum of Kraków changed its price list on 2 January 2026. The current list for the Rynek Underground, per its branch page:

• Normal ticket: 45 PLN.
• Reduced ticket: 35 PLN, for pupils and students, people over 65, retirees, and people with disabilities and their carers, among others.
• Family ticket: 90 PLN, for up to four people, meaning two adults with one or two children under 16, or one adult with two or three children under 16.
• School groups: 26 PLN per person.
• Guided tour of the exhibition: 350 PLN per group, on top of the entry tickets.

Children under 7 go in free. Group tickets at this branch start at 10 people, though a party of 10 to 15 still visits as individuals; from 16 people you book as a group. If you hold a Kraków Card, the museum's discount page lists 20 percent off normal and reduced tickets, though not on top of other promotions; whether the card pays for itself is a separate question, covered in our Kraków Card review.

One warning about tickets bought at the box office: they are non-refundable. Online tickets can be returned under the museum's online sales terms, which is one more reason to buy online.

Opening hours and the days it is closed

Hours differ by day of the week, and the free day is also the short day.

• Monday, Wednesday, Thursday: 10:00 to 19:00.
• Tuesday: 10:00 to 15:00, the free admission day.
• Friday, Saturday, Sunday: 10:00 to 20:00.

The museum is closed on the second Monday of every month, and on a list of dates published on its branch page, which in the coming months includes 1 November, 11 November, 16 to 18 November and 24 and 25 December. On 31 December it opens from 10:00 to 15:00. Last admission is 75 to 80 minutes before closing: the branch page says 75, the visiting rules in force since 1 July 2026 say 80 for individual visitors and 90 for groups. Either way, arriving at 18:30 on a Monday will not work.

Free entry on Tuesdays, and why it can backfire

Tuesday is the free day for the permanent exhibition, and the museum runs it on strict terms. There is no advance booking for individual visitors on free days. Free tickets are handed out at the branch box office on the day, in order of arrival, from a limited pool, and one person can collect at most five. Each free ticket still carries a start time, and the museum can cancel it if you do not begin your visit within 15 minutes of that time.

Add the short opening hours, 10:00 to 15:00, and the arithmetic is simple. If you want a free visit in high season, be at the box office when it opens, expect a queue, and have a plan B for the afternoon. If your time in Kraków is worth more than 45 PLN, go on another day.

How to book, and where the entrance is

Tickets are sold online at bilety.muzeumkrakowa.pl, at the branch box office at Rynek Główny 1, and at the museum's Visitor Centre in the Krzysztofory Palace at Rynek Główny 35. Every ticket carries an entry time, and the visiting rules say plainly that failing to book or buy in advance "may result in you being unable to enter the Exhibition". In July and August that sentence is not a formality.

The address, Rynek Główny 1, does not tell you which side to go to. The museum's own plan of the ticket office and entrance puts them on opposite sides of the Cloth Hall. The ticket office is on the western side, facing the Town Hall Tower, which is the "entrance opposite Szewska Street" of the visiting rules. The entrance to the exhibition is on the eastern side, facing St Mary's Basilica. Get your ticket on the west side first, then walk round. At the box office the museum recommends paying by card.

What you will see down there

The route runs between the stone and brick walls of former merchant stalls and past the foundations of the Cloth Hall, with cross-sections of the soil layers and fragments of medieval roads left exposed. The objects come from the excavation itself: 14th-century coins, jewellery, pottery, dice, toiletry items used over 600 years ago, Tartar arrowheads, and beads and medallions traded in from the East.

The museum's own list of highlights includes a silver denarius minted by Władysław Łokietek in the early 14th century, a 14th-century silk purse, a bone knife handle carved as a human figure, and an 11th-century pendant and cross from Byzantium. Then there is the object everyone remembers: a lead ingot weighing 693 kilograms, known locally as a "loaf", which the museum describes as the only one of its kind in the world.

Around the finds sit models of Kraków around the year 1500, of St Mary's Basilica at different stages of its building, and of the 12th-century settlement, plus the multimedia the museum is known for. Its route description counts 37 touchscreens, 27 projectors, 38 screens, 4 holograms and 104 media players, with content in several languages. There is a playroom and a mechanical theatre telling a Kraków legend for younger children.

How long it takes and how to plan the visit

The museum does not publish a visit time for individual visitors. Two of its numbers set the frame, though: a guided tour of the exhibition lasts about 75 minutes, and last admission is 75 to 80 minutes before closing. Allow an hour if you read little and closer to 90 minutes if you read everything and let children use the screens.

Four rules from the regulations matter in practice:

• You follow a set one-way route, and once you leave the exhibition you cannot re-enter.
• Rucksacks and large luggage over 30 litres are not allowed in, and neither are long umbrellas. If you arrive with a suitcase, sort out luggage storage in Kraków first.
• Individual visits cover groups of 1 to 15 people. Anything from 16 to 30 counts as a group and books as one.
• The exhibition has a threshold-free entrance, ramps and a lift, and an accessible toilet, per the museum's accessibility page.

It is underground and out of the weather, which makes it one of the better answers to a wet afternoon. Our article on Kraków in December lists it among the museums to keep for a rainy day for exactly that reason.

Guided tours, groups and the combined ticket

A guided tour with a museum guide costs 350 PLN per group plus entry tickets, must be booked at least four days ahead through the ticket site, and covers at most 30 people including supervisors. The guide waits 15 minutes past the booked time and then leaves. Cancelling less than four days before the date, or not cancelling at all, triggers a contractual penalty of 250 PLN. Outside guides may lead visits only with an authorisation issued by the museum.

The visiting rules also mention a combined "Medieval Kraków" route ticket that covers the Rynek Underground together with the Town Hall Tower and the Barbican, sold while that route is open. The museum's route page describes it as one ticket for four medieval sites. The rules do not say when the route is open, so ask at the box office if you plan to climb the tower's 110 steps on the same day.

Is it worth it, and for whom

Yes, for anyone who wants to understand the square rather than just photograph it. The museum shows the same place from underneath, and the story of the 1241 invasion and the 1257 charter explains why the Old Town looks the way it does. It is also the most comfortable of Kraków's big museums in bad weather.

Skip it if you have a single afternoon and have not yet seen Wawel or Kazimierz, or if you dislike dim spaces and screens. Families with children under seven or so tend to move through quickly; older children usually do better. If your interest is the 20th century rather than the 13th, the Schindler's Factory museum is run by the same institution and will hold you longer.

Pair the visit with the ground level. Our guide to the Main Market Square covers what stands above the museum, from the Cloth Hall to the trumpet call. If walking the rest of the Old Town on the same day sounds like too much, the Old Town electric cart tour passes the square, Collegium Maius and Wawel in about 40 minutes with a guide. The Kraków guide has the rest of the practical planning.
