Old Town Square and Astronomical Clock Tickets, Prices & Opening Hours 2026: Visitor Guide
Tower admission to the Old Town Hall and Astronomical Clock costs 350 CZK for adults in 2026, with an optional 100 CZK surcharge if you'd rather take the elevator than climb to the 42-meter gallery, and the clock's famous hourly show — the Walk of the Apostles — runs every hour from 9:00 to 23:00, free to watch from the square below. That split matters: the show itself costs nothing, while climbing the tower behind it for the rooftop panorama over the square's spires is a separate, paid exhibit.
This guide breaks down exactly what a 2026 visit costs, when the tower and clock are open, how long to realistically budget, and how to avoid queuing at the wrong window. It's part of our full Prague attractions guide.
What Is Old Town Square and the Astronomical Clock?
Old Town Square (Staroměstské náměstí) has been Prague's central public space since the 10th or 11th century, when it formed around a marketplace at the crossing of trade routes into Bohemia. It's ringed by Gothic and Baroque facades — the twin spires of the Church of Our Lady before Týn, the Baroque St. Nicholas Church, and the Old Town Hall, whose tower anchors the square's southwest corner and carries the Astronomical Clock on its south-facing wall.
The clock — known locally as the Orloj — was installed in 1410 by clockmaker Mikuláš of Kadaň with input from astronomer Jan Šindel, and is the oldest astronomical clock in the world still operating. The main dial functions as a medieval astrolabe, tracking the sun and moon against a zodiac ring and displaying three separate time scales at once. A calendar dial below it, added around 1490, cycles through the months and a fixed calendar of saints' days.
Its best-known feature is the Walk of the Apostles, added in the 1860s: on the hour, wooden figures of the Twelve Apostles process past two small windows above the dial while a skeletal figure representing Death tolls a bell — the whole sequence lasts under a minute. The clock suffered serious damage during the Prague Uprising in May 1945, when gunfire destroyed its wooden sculptures and calendar dial; it was repaired by 1948, and a 2018 restoration reinstated the original 1860s-era mechanism in place of a later electric drive.
Tickets & Prices 2026
As of mid-2026, the Old Town Hall Tower and Knights' Hall exhibition (including a digital model of the clock mechanism) is priced at 350 CZK for adults, 280 CZK for youth aged 16–26, and 230 CZK for children aged 6–15. A family ticket covering two adults and up to four children runs 750 CZK, children under 5 enter free, and ZTP/P disability card holders enter free with one companion. That base ticket includes the climb to the 42-meter viewing gallery by stairs; riding the elevator instead adds 100 CZK for adults and youth, or 50 CZK for seniors 65 and over.
Two optional guided circuits cover the Old Town Hall's historic interior rather than the tower: Circuit A (chapel, ceremonial halls, underground) adds 150 CZK, and Circuit B (underground only) adds 100 CZK. Online skip-the-line tickets run at a premium over walk-up prices — roughly 450 CZK adults, 300 CZK seniors, 360 CZK youth, 900 CZK family — reflecting priority-entry convenience rather than a discount, so weigh whether skipping the line is worth the markup for your dates. Confirm current tiers on the official Prague City Tourism ticket page before booking.
None of this applies to simply watching the clock. The Walk of the Apostles show is visible free from anywhere in Old Town Square — no ticket, no line, no time slot. If you're deciding between a multi-attraction Prague pass and paying individually, the tower is one of the cheaper stand-alone tickets in the city center, which changes the math on whether a bundled pass pays for itself.
Opening Hours & Best Time to Go
The tower runs on two seasonal schedules: 10:00–19:00 daily from January through March, and 09:00–20:00 daily from April through December. Hours are modified around Christmas, roughly December 24 through early January, so check the official page if visiting over the holidays. The Apostles show runs on the hour from 9:00 to 23:00 year-round, independent of the tower's own hours — you can catch it in the evening even after the tower has closed to ticketed visits.
The square is the meeting point for most of Prague's walking tours, so it's busiest from roughly 10:00 to 17:00, especially on the hour when groups cluster for the Apostles parade. Arriving before 9:30 or after dinner gives noticeably more breathing room for photos and the tower queue. The first hour after the tower opens each day also carries a 50% early-bird discount on admission.
How Long to Plan
Watching a single Apostles show and photographing the square takes 15–20 minutes and needs no ticket. A full tower visit — the climb or elevator ride, time on the 42-meter gallery, and the Knights' Hall exhibition — runs 45–60 minutes at a comfortable pace. Adding Circuit A or B extends a visit by another 45–60 minutes, since both cover a separate route through the Old Town Hall's historic rooms and cellars.
Treating Old Town Square as one stop on a broader walk through the historic core — the square itself, the Týn Church exterior, the Jan Hus Memorial, and a coffee stop — is realistically a 1.5- to 2-hour block once the tower is included. If you're mapping the square into a wider day, our 2-day Prague itinerary shows where it fits alongside the castle district and the river crossing.
How to Get There
The closest metro stop is Staroměstská on Line A (green), a 5-minute walk through the Old Town's lanes. Můstek (Lines A and B) is a slightly longer walk down Melantrichova street and suits arrivals from Wenceslas Square. Several tram lines stop near náměstí Republiky, a short walk northeast.
On foot, the square sits roughly 5–7 minutes from Charles Bridge via the pedestrianized Karlova street, making the two a natural pairing on the same walk. Driving is not practical: the historic core is pedestrianized or heavily traffic-restricted, with no useful on-street parking near the tower entrance.
Visit Tips: Queues, Booking & Common Mistakes
Book tower tickets online ahead of time during summer, Christmas market season, and Easter — the walk-up queue for the elevator can run well past 20–30 minutes at midday in high season, even though the free show never has a line. Reserving online also gets you the priority entrance rather than the general ticket window.
The most common mistake is expecting more from the free Apostles show than it delivers — it's a roughly 30-second parade of small wooden figures, and first-timers sometimes push to the front of a packed square only to find it's over in seconds; watching from a slight distance or a café terrace works just as well. A second mix-up is assuming tower admission includes Circuit A or B — those interior tours of the Old Town Hall are priced and booked separately.
The square is also one of Prague's most consistently flagged spots for pickpocketing at the top of each hour — keep bags zipped and in front. At 42 meters, the gallery is fully exposed to wind, so a layer is worth carrying even in summer.
Nearby Attractions
The Prague Jewish Quarter (Josefov) borders the square directly to the north and is walkable in a few minutes, making it an easy add-on before or after the tower. South via Karlova street, the Charles Bridge is a 5–7 minute walk and pairs naturally with an Old Town morning.
Across the river, Prague Castle is roughly 20–25 minutes on foot or a short tram ride, and most visitors combine the square and the castle district into the same full day rather than trying to do both back to back without a break.
Frequently Asked Questions
Frequently Asked Questions
How much are tickets for the Old Town Hall Tower and Astronomical Clock in 2026?
As of mid-2026, standard adult admission to the Old Town Hall Tower is 350 CZK, with youth (16–26) at 280 CZK and children (6–15) at 230 CZK. A family ticket for two adults and up to four children is 750 CZK. The elevator adds 100 CZK for adults and youth, or 50 CZK for seniors. Confirm current prices on the official Prague City Tourism ticket page before booking.
What time does the Astronomical Clock show run?
The Walk of the Apostles runs every hour from 9:00 to 23:00 daily, year-round, and is free to watch from Old Town Square. It runs on this schedule independently of the tower's own opening hours, so it's viewable even in the evening after the paid tower exhibit has closed.
Is Old Town Square free to visit?
Yes. Walking around Old Town Square and watching the Astronomical Clock's hourly show costs nothing. Admission fees only apply if you climb the Old Town Hall Tower for the rooftop gallery view, or add one of the guided Circuit A or B tours of the hall's historic interior.
How long does it take to visit the Astronomical Clock and tower?
Watching one Apostles show and photographing the square takes 15–20 minutes. A full tower visit, including the climb or elevator and the Knights' Hall exhibition, adds 45–60 minutes. Budget 1.5–2 hours total if you're treating the square as one stop on a wider Old Town walk.
Do I need to book Old Town Hall Tower tickets in advance?
It's recommended in peak season. Walk-up queues for the tower elevator can exceed 20–30 minutes at midday during summer and the Christmas markets, while online tickets get priority entry — though they're sold at a premium over the walk-up price, so weigh the markup against how much time you want to save.
Old Town Square rewards a visit at almost any hour, but the two experiences on offer here are genuinely different: the free Apostles show is a quick, crowded moment on the hour, while the paid tower climb is a slower, quieter payoff with the best rooftop view of the square's spires in Prague. Knowing which one you actually want — or booking time for both — is most of the planning.
For 2026, arrive before 9:30 or after the dinner rush to see the square with fewer crowds, book tower tickets online if you're visiting in summer or over the Christmas markets, and treat the free show as a quick highlight rather than the main event.
