Strasbourg Cathedral (Cathédrale Notre-Dame de Strasbourg) is a Gothic masterpiece at the heart of Strasbourg's old town (the Grande Île, a UNESCO World Heritage Site since 1988) in Alsace, built from the region's pinkish Vosges sandstone. Its 142 m spire made it the world's tallest building from 1647 to 1874, and its striking silhouette is asymmetrical: the planned south tower was never built, leaving a single spire on the north side. It is famed for its Renaissance astronomical clock, whose parade of automated apostles animates every day at 12:30 pm. In summer 2026 (4 July–30 August) the west facade hosts 'Opus 800', a free evening sound-and-light show marking the 800th anniversary of the Œuvre Notre-Dame foundation. Entry to the cathedral is free but involves a security check, while the astronomical clock viewing and the panoramic tower platform are ticketed with limited hours, so it pays to plan ahead.

Good to know
SafetyWatch for pickpockets in crowded spots such as the cathedral square, the trams and the Christmas market. Carry your bag in front with the zip closed, and stay alert during the busy summer evenings of the Opus 800 show.
SeasonThe summer peak and Opus 800 (July–August), plus the December Christmas market, get very crowded. The astronomical clock queue builds from about 11:30 am in summer and the tower platform can back up in the afternoon, so aim for early morning or late afternoon.
RulesThe clock's full automata performance runs only once a day, at 12:30 pm (except Sundays and feast days with an 11 am Mass), preceded by an introductory video at noon. Tickets are sold the same morning at the cathedral booths and can sell out, so arrive early.
RulesEntry to the cathedral is free but a security check at the door means bags should be opened in advance. The astronomical clock and the tower platform are separately ticketed, and prices and hours change by season, so always confirm the latest details on the official site (closed 1 Jan, 1 May, 25 Dec).
MannersThis is a working church with Masses, so keep quiet and avoid flash photography during services. Men are asked to remove hats on entering, and overly revealing clothing is best avoided out of respect.
CautionBuy clock and platform tickets only at the cathedral's official booths or entrance. Decline unofficial ticket sellers, petition-signing approaches and forced 'friendship bracelet' offers around the tourist squares.
Practical info
Take CTS tram lines A or D to 'Langstross Grand'Rue' (about a 1-minute, 100 m walk), or walk roughly 15 minutes from the main station (Gare). Entry to the interior is free (Mon–Sat 08:30–11:15 and 12:45–17:45; Sundays and feast days afternoons only), while the astronomical clock and the tower platform need separate tickets; because fees and hours vary by season, check the latest information on the official site (cathedrale-strasbourg.fr) just before you go.
