St. Mary's Basilica (Polish: Bazylika Mariacka / Kościół Mariacki) is a brick-Gothic church towering over the Main Market Square (Rynek Główny) in Kraków's Old Town, rebuilt in 1355–1365 under King Casimir III the Great on 13th-century foundations. It is world-famous for the Veit Stoss (Wit Stwosz) altarpiece — the largest Gothic wooden altarpiece in the world — and for the Hejnał, a trumpet call sounded to all four compass points from the taller tower every hour on the hour. In 2026 it remains an active, living place of worship and one of Kraków's defining landmarks, visited via a dedicated tourist entrance on the south side outside Mass times. The daily ceremonial opening of the altarpiece at 11:50 is the highlight of any visit, so time your entry accordingly.
The Veit Stoss altarpiece — carved 1477–1489, the largest Gothic wooden altarpiece in the world (about 13 m tall, over 200 carved figures). Its ceremonial opening on weekdays at 11:50 is the visit's centerpiece.
The Hejnał Mariacki — the hourly trumpet call played from the taller tower (about 80 m) to the four directions; the melody breaks off mid-note in memory of a bugler shot in the throat while warning of a Mongol (Tatar) attack.
The deep-blue, star-studded vaulted ceiling and Jan Matejko's polychrome murals adorning the presbytery.
Stained-glass windows in the presbytery designed by Stanisław Wyspiański and Józef Mehoffer.
The asymmetrical twin towers — the two unequal spires form the church's iconic silhouette; the taller tower can be climbed on foot.
Good to know
CautionPickpockets work the crowds on the Main Market Square, especially when people gather for the 11:50 altarpiece opening. Wear your bag in front and keep your wallet, passport, and phone in an inside pocket.
RulesVisiting the church and climbing the tower (Hejnalica) require separate tickets, entrances, and hours. Church tickets are sold at Plac Mariacki 7; the tower entrance is on the Floriańska Street side. Always confirm current prices and times on the official website before your visit.
RulesThis is an active church with real Masses, so tourist entry is restricted in the mornings and before 2 pm on Sundays. You cannot sightsee during Mass, so check opening times in advance.
MannersAs a place of worship, dress modestly with shoulders and knees covered, and stay quiet inside. Avoid photography and flash during services, and follow posted guidance.
SeasonJuly and August are peak season with very large crowds and summer heat. To see the 11:50 altarpiece opening, be inside by about 11:30 to get a spot; an early-morning visit is far calmer.
SafetyThe taller tower is reached by a narrow, steep spiral staircase (around 270 steps) with no elevator, which is demanding on knees and stamina. For safety, children under 7 are not allowed up, and group size (about 15 people) is limited.
Practical info
The Old Town is pedestrianized, so ride a tram or bus to a nearby stop and walk in; enter the church through the dedicated tourist door on the south side of the Main Square. Opening hours (roughly Mon–Sat 11:30–18:00, Sun & holidays 14:00–18:00) and ticket prices can change, so confirm the latest details on the official website (mariacki.com) before visiting.
