🏛️ Heritage & castles
Castles, cathedrals and citadels of the Grand Est
The Grand Est has a rare concentration of monuments: the cathedrals of Strasbourg, Metz, Reims, Troyes, Toul and Châlons, the royal squares of Nancy and Charleville-Mézières, fortified castles perched in the Vosges, and citadels built along the kingdom’s successive frontiers. Several ensembles are UNESCO World Heritage listed, including Place Stanislas, Place de la Carrière and Place d’Alliance in Nancy and the coronation sites in Reims. This page helps you choose according to the season, as opening times vary greatly from one month to the next.
Two kinds of visit complement each other. The cathedrals, the squares and a few major castles run by local authorities, such as Haut-Koenigsbourg, can be visited all year round. The ruins of the Vosges, freely accessible on foot, are best suited to walks from spring to autumn. On the other hand, many castles run by associations or by the département close in winter: Hohlandsbourg, Fleckenstein (apart from a few afternoons), the Citadel of Bitche, Malbrouck and Sierck. Always check opening times on the official website before setting off, especially between November and March.
What to do this month?
Pick a month: our seasonal ideas and a tip to make the most of it.
January: The quietest month: most association-run castles are closed. Focus on the cathedrals and on Haut-Koenigsbourg (closed on 1 January, free on the first Sunday). Sedan Castle usually opens only at weekends in January outside the school holidays.
February: Still off-season for the fortresses: Fleckenstein opens only on Sunday afternoons (except in snow or ice). The Citadel of Bitche reopened at weekends from late February in 2026; the 2027 date is still to be confirmed.
March: A gradual return: the Citadel of Bitche resumes its seasonal hours around March and Fleckenstein reopens daily in late March (27 March in 2027). A good month for Lorraine’s cathedrals, still little visited.
April: Many castles open for the season: Hohlandsbourg (early April in 2026), Malbrouck (season from April to the autumn) and the guided tours of Haroué resume. Sierck Castle also reopens after its winter closure.
May: Ideal for the hilltop ruins of the Vosges, reached on foot along waymarked trails, before the summer heat and crowds. Combine a castle in the vineyards with Mont Sainte-Odile.
June: Long days for the fortresses of the borderlands: the Northern Vosges (Fleckenstein, La Petite-Pierre) or the strongholds of northern Lorraine and the Ardennes, such as Montmédy and Rocroi.
July: Peak season: extended hours and events at the major castles. Fort de Mutzig offers daily tours in summer; arrive early at Haut-Koenigsbourg, which gets very busy.
August: To escape the crowds in Alsace, explore the Ardennes (Sedan, Place Ducale, Rocroi, Givet) or Champagne and its cathedrals with their great stained-glass windows.
September: The month of the European Heritage Days (third weekend): a chance to visit places rarely open to the public, such as Clairvaux Abbey or the Château de Brienne. Booking recommended.
October: Last weeks of the season: Hohlandsbourg, Fleckenstein and Fort de Mutzig close or reduce their hours in early November. The ruins in the vineyards are at their best in autumn colours.
November: Many castles close (Fleckenstein is closed from 2 November to 25 December 2026). Still open: Haut-Koenigsbourg, free on the first Sunday, the cathedrals and the Château de Lunéville.
December: Christmas market season: pair cathedrals with old town centres. In Sélestat, the Humanist Library usually hosts an exhibition on the history of the Christmas tree. Haut-Koenigsbourg closes on 25 and 26 December; Fleckenstein reopens in the afternoons from 26 December to 3 January.

Our tips
- In winter, stick to sites open all year round: Haut-Koenigsbourg Castle is closed only on 1 January and 25 and 26 December, and admission is free on the first Sunday of the month from November to March.
- Leave the pushchair in the car: at Haut-Koenigsbourg the tour involves around 300 steps and pushchairs are not allowed; the ruins of the Vosges are reached on footpaths.
- For the hilltop ruins (Haut-Barr, Haut-Andlau, Saint-Ulrich, Frankenbourg), wear good shoes and avoid icy days: several sites close or advise against access in snow or ice.
- Consider the Pass’Alsace or the Museums-PASS-Musées if you are visiting several Alsace sites in a row: Haut-Koenigsbourg accepts both (check the conditions on their websites).
- The European Heritage Days, on the third weekend of September, open up places that are rarely accessible, such as Clairvaux Abbey or the Château de Brienne; book guided tours early.
- The Palace of Tau in Reims is closed while it is transformed into a museum of the coronations (musée des Sacres): in Reims, focus on the cathedral and the Basilica of Saint-Remi, and follow news of the reopening on the Centre des monuments nationaux website.
