Castles and chateaux in Switzerland: the essential guide

Switzerland’s castles: a surprising heritage

Most visitors come to Switzerland for the mountains, the trains, and the lakes. Many are genuinely surprised to find a country dense with medieval fortifications — over 200 castles, towers, and fortified houses spread across a territory smaller than the state of South Carolina. That density reflects Switzerland’s position at the heart of medieval European power struggles. Alpine passes were the arterial routes of the continent, and whoever controlled them controlled trade, armies, and tribute.

The Swiss castles that survive today range from imposing lakeside fortresses associated with the counts of Savoy to the three UNESCO-listed towers of Bellinzona guarding the southern approach to the Gotthard Pass. Many are free or low-cost to enter; several can be visited on a round trip in a single day from major Swiss cities. This guide covers the standout sites, how to reach them, and what makes each one worth the journey.

Chateau de Chillon, Montreux

Chateau de Chillon is the most visited historic monument in Switzerland, and once you see it, the reason is immediately obvious. The castle sits directly on a rocky island in Lake Geneva, connected to the shore by a narrow bridge, with the Savoy Alps rising behind it and the water of the lake surrounding it on three sides. The visual impact is so precisely what a medieval castle should look like that many visitors mistake it for a stage set.

It is entirely real. Construction began in the 9th century, and the castle reached its present form under the Counts of Savoy in the 13th and 14th centuries, serving as a strategic control point over the road from Burgundy across the Alps to Italy. The Dukes of Savoy used it as a summer residence and as a prison; the most famous prisoner was Francois Bonivard, a Genevan prior who was chained in the dungeon between 1530 and 1536 for his political opposition to Savoy. Lord Byron visited in 1816, saw the worn groove in the pillar where Bonivard’s chain was attached, and wrote The Prisoner of Chillon the same night, turning the castle into one of the most celebrated sites of Romantic literature.

Inside, the castle is exceptionally well preserved. Fourteen centuries of occupation mean the rooms have retained original frescoes, carved ceilings, and Gothic windows overlooking the lake. The great hall, the chapel with its 14th-century murals, the underground passages, and the dungeon where Bonivard paced are all accessible. The self-guided tour is well-signposted in multiple languages.

Book your Chateau de Chillon entrance ticket online to avoid queues, particularly in summer when the castle can be extremely busy.

Getting there: From Montreux, take bus 201 (approximately 8 minutes) or the lake promenade walk (45 minutes). From Villeneuve, take the train and walk 10 minutes. The castle is not covered by the Swiss Travel Pass for entry, though the Swiss Travel Pass covers transport to reach it.

Practical details: Open daily from 09:00, closing times vary by season (18:00 in summer, 17:00 in winter). Adults CHF 16.50, children CHF 8. Allow 90 minutes to two hours.

Gruyeres Castle, Gruyeres

Gruyeres Castle sits at the top of the village of Gruyeres — itself one of the most picturesque medieval villages in Switzerland — with panoramic views across the pre-Alpine foothills and the Moléson peak. Built between the 11th and 16th centuries as the seat of the Counts of Gruyères, the castle passed through several owners after the counts went bankrupt in 1554 and eventually became cantonal property in 1849.

The interior has been thoughtfully arranged to reflect different periods of the castle’s occupation. Medieval halls with tiled floors and painted heraldic decorations occupy the lower floors; the apartments used by the Bovy family (Geneva patrons of the arts who owned the castle in the 19th century) are furnished in a Romantic style and decorated with Swiss landscape paintings. The tower offers views that justify the climb.

The village of Gruyeres is pedestrianised and lined with restaurants serving fondue and raclette — the cheese of the same name is produced in the surrounding valleys. A visit to the castle pairs naturally with a stop at the HR Giger Museum in the village (dedicated to the Swiss artist who created the Alien franchise’s visual aesthetic, incongruously housed in a Gothic chateau a few metres from the castle entrance).

Getting there: Train from Gruyères station (reached from Bulle, which connects to Fribourg and Lausanne). The village is a 20-minute uphill walk from the station, or take the connecting bus. The Swiss Travel Pass covers transport.

Practical details: Open daily 09:00-18:00 (summer), 10:00-17:00 (winter). Adults CHF 12, children CHF 6. Allow two hours including the village.

Thun Castle, Thun

Thun Castle (Schloss Thun) sits on a hill directly above the old town of Thun, reachable by a covered wooden staircase of over a hundred steps from the market square. The keep — a square Romanesque tower dating to the late 12th century — is flanked by four corner turrets and houses the Historisches Museum Thun, one of the best regional history museums in the Bernese Oberland.

The museum’s collection spans prehistoric and Roman finds from the region, medieval weapons and armour, decorative arts, and an extensive display of Swiss faience pottery. The views from the tower over Thun’s red rooftops, Lake Thun, and the Bernese Alps beyond — with the Niesen pyramid particularly prominent — are among the finest of any castle viewpoint in Switzerland.

Thun itself is a rewarding town often bypassed in favour of nearby Interlaken. The covered walkways along the first-floor level of the arcaded main street, the wooden bridge over the Aare, and the compact old town make for a pleasant half-day exploration.

Getting there: Direct train from Bern (20 minutes) or Interlaken (20 minutes). The castle is a 15-minute walk from Thun station via the old town. Covered by Swiss Travel Pass for transport.

Practical details: Open daily 10:00-17:00 (February to April and October), 10:00-18:00 (May to September). Adults CHF 12, children CHF 6. Closed November to January. Allow 90 minutes.

Bellinzona’s three UNESCO castles

Bellinzona, the capital of the canton of Ticino, guards the southern approach to the Gotthard and San Bernardino passes — the two most important crossings between Italy and northern Europe. Whoever controlled Bellinzona controlled the passes, and the Visconti dynasty of Milan, the Swiss Confederation, and the Dukes of Milan each built and extended the three fortresses that still crown the town’s hills.

All three castles — Castelgrande, Montebello, and Sasso Corbaro — along with the connecting walls were inscribed on the UNESCO World Heritage List in 2000, cited as the finest example of medieval military architecture in the Alps.

Castelgrande is the oldest and largest, occupying the flat-topped rocky outcrop that juts from the town centre. A lift from the town square shoots up through the rock to the castle terrace. Two towers, the Black and White towers, date from the 13th and 14th centuries respectively. The castle restaurant is one of the best in Ticino, with a terrace offering panoramic views.

Montebello sits on the hill immediately east of Castelgrande, connected by a restored section of medieval wall. The castle contains a well-presented museum of local archaeology and medieval artefacts. The walk between Castelgrande and Montebello along the walls takes about 20 minutes.

Sasso Corbaro stands higher and more isolated, a 45-minute walk from Montebello up a steep path. Built in 1479 in just six months as an emergency military measure, it has a more austere character than the other two. The views from its terrace extend the full length of the Ticino valley.

Getting there: Direct train from Lugano (30 minutes) or Zurich (via Gotthard, approximately 2 hours). Bellinzona is easily reachable on the Swiss Travel Pass.

Practical details: All three castles open Tuesday-Sunday 10:00-18:00 (April to October), Tuesday-Sunday 10:00-17:00 (November to March). Combined pass for all three adults CHF 15, children CHF 8. Individual entry also available. Allow a full day to see all three properly.

Habsburg Castle, Aargau

The ruins of Habsburg Castle in the canton of Aargau have a historical significance disproportionate to their modest scale: this was the ancestral seat of the House of Habsburg, the dynasty that went on to rule the Holy Roman Empire, Austria-Hungary, Spain, and much of Latin America for over six centuries. The name Habsburg means “Hawk’s Castle,” and the 11th-century tower visible from the road outside the village of Habsburg is the origin point of one of history’s most consequential noble families.

The castle fell into ruin after the Habsburgs lost control of Swiss territories in the 14th century and transferred their power base to Vienna. The ruins were partially restored in the 19th century in Romantic style, and today the site houses a small restaurant and exhibition on Habsburg history. It is a relatively modest castle by Swiss standards — the historical resonance rather than the architecture is the draw.

Getting there: Train to Brugg AG from Zurich or Basel (direct), then bus or cycle path to the castle (approximately 5km). Allow half a day from either city.

Practical details: The grounds are open year-round. Restaurant open Wednesday-Sunday. No entry charge for the ruins. Allow 90 minutes.

Tourbillon Castle, Sion

Sion (Sitten in German), the capital of Valais, is dominated by two hills rising abruptly from the valley floor, each crowned with a historic monument. The Valere Basilica on the right-hand hill is more famous — it houses the world’s oldest playable organ, dating to the 14th century. But Tourbillon Castle on the left-hand hill, ruined by a fire in 1788, is the more dramatically situated of the two.

The steep path up to the castle ruins takes about 25 minutes from the town centre and rewards the effort with views extending across the Rhône valley in both directions. The castle walls, towers, and the shell of the chapel remain, and the site is freely accessible. The combination of Tourbillon and Valere can be done in a half-day, and Sion itself — with its old town, cave-aged wines from the local vineyards, and proximity to the ski resorts of Crans-Montana — makes a worthwhile base.

Getting there: Direct train from Bern (90 minutes), Lausanne (60 minutes), or Zermatt (90 minutes). Swiss Travel Pass covers transport.

Practical details: Open daily during daylight hours. Free entry. Allow 90 minutes for both hills.

Rapperswil Castle, Lake Zurich

Rapperswil, a small town on the south shore of Lake Zurich reached in 40 minutes from Zurich by S-Bahn, is sometimes called the Town of Roses for its municipal rose garden. The 13th-century castle on the hill above the harbour houses a museum of Polish history — a surprising subject, explained by the strong historical connection between exiled Polish communities and Rapperswil in the 19th and early 20th centuries.

The castle’s exterior and terrace are the main draw. The view across Lake Zurich from the battlements, with the Alps visible in the distance on clear days, is one of the better lakeside castle views in eastern Switzerland. The old town below the castle has several good restaurants and cafés.

Getting there: S-Bahn S5 from Zurich Hauptbahnhof (40 minutes). Free travel with Swiss Travel Pass.

Practical details: Castle museum open Thursday-Sunday 13:00-17:00 (April-October). Adults CHF 6. The castle exterior and terrace can be viewed freely. Allow 90 minutes including the old town.

Munot Fortress, Schaffhausen

Schaffhausen’s Munot fortress is a circular Renaissance fortification built between 1564 and 1589 using forced labour — the townspeople were required to contribute working days to its construction, a system known as Frondienst. The circular design, based on a treatise by Albrecht Dürer on ideal fortification geometry, was unusual for its time.

The Munot sits at the eastern end of Schaffhausen’s old town, connected to it by a long defensive wall. Visitors can walk up through the fortification, out onto the great round roof with its crenellated parapet, and enjoy views over the Rhine and the old town. The watchman who lives in the tower still rings the great bell every evening at 21:00 — a tradition maintained since the Middle Ages.

Schaffhausen itself, with its richly frescoed facades and Rhine Falls nearby, is one of Switzerland’s most underrated day trips from Zurich (50 minutes by train).

Getting there: Train from Zurich to Schaffhausen (50 minutes). Swiss Travel Pass valid. The fortress is a 15-minute walk from the station through the old town.

Practical details: Open daily May-September 08:00-20:00; October-April 09:00-17:00. Free entry. Allow 60-90 minutes including the old town approach.

Aigle Castle, Chablais

Aigle Castle guards the entrance to the Chablais wine region at the point where the Rhône plain narrows between mountains on the approach to the Lake Geneva shore. Built in the 13th century and substantially extended by the Bernese after they conquered the region in 1475, the castle now houses the Musée de la Vigne et du Vin (Museum of Wine and Vine), which covers the history of viticulture in the Valais and Vaud cantons.

The museum is engaging for anyone interested in wine — the medieval cellar below the castle contains large wooden barrels and original wine-making equipment — but the castle’s main appeal is its setting: vineyards on all sides, the Rhône visible from the towers, and the mountains rising steeply behind. October visits coincide with the grape harvest.

Getting there: Train to Aigle from Lausanne (35 minutes) or Montreux (15 minutes). Swiss Travel Pass covers transport.

Practical details: Open Tuesday-Sunday 10:00-18:00 (April-October), Tuesday-Sunday 10:00-17:00 (November-March). Adults CHF 10, children CHF 5. Allow 90 minutes.

Planning a Swiss castle route

Switzerland’s compact geography makes it straightforward to visit multiple castles in a single trip. Several natural combinations work well:

Lake Geneva loop: Chillon (Montreux) and Aigle can be done in a single day from Lausanne or Montreux. The train journey between them is 15 minutes.

Bern region: Thun Castle pairs with a half-day in Thun and a boat trip on Lake Thun. From Thun, the train to Bern takes 20 minutes for onward connections.

Ticino: Bellinzona’s three castles are a full day in themselves. Base in Lugano for access to the Italian lake region.

Eastern Switzerland: Schaffhausen’s Munot and the Rhine Falls, combined with the Habsburg ruins near Brugg, can make a satisfying day trip from Zurich. The drive or train journey circles the northern part of Switzerland through countryside rarely visited by foreign tourists.

For winter itineraries and family visits, many of these castles are accessible year-round and provide excellent indoor-outdoor combinations when mountain activities are not possible. Check opening hours carefully in the November-March period, as some smaller castles reduce their schedules or close entirely.

The Swiss Travel Pass makes reaching all of these sites by public transport economical. Castle entry fees are separate but generally modest. A week-long castle-focused itinerary is entirely feasible and would barely scratch the surface of Switzerland’s medieval heritage.
