Rapperswil Castle

Rapperswil Castle stands on a rocky promontory at the narrows of Lake Zurich (Obersee), above the town of Rapperswil-Jona in the canton of St. Gallen, approximately 40 kilometres east of Zurich. The castle's position on the promontory — with lake water visible on three sides and the medieval town grid below — gives it the visual quality of a lake island castle while remaining connected to the mainland. The wooden pedestrian bridge across the narrows at this point, originally a medieval crossing and reconstructed in its current 841-metre form in 1878, was the reason the castle was built here: controlling the land route across the upper Lake Zurich narrows was the strategic purpose of the medieval fortification.

The castle was built around 1220 by the Counts of Rapperswil, a comital family of regional importance in the upper Lake Zurich area. Ownership passed through Habsburg hands and then to the Toggenburg counts across the 13th and 14th centuries. During the Old Zürich War (1436–1450) — one of the most destructive internal Swiss conflicts of the 15th century, fought between Zurich in its Habsburg alliance and the Swiss Confederation with French support — Rapperswil was besieged by Confederation forces in the 1440s and partly destroyed. The rebuilding after the siege produced the castle's current three-tower form on its rocky outcrop. After Zurich's submission to the Confederation ended the war, Rapperswil entered a period of Swiss Confederation administration and lost its earlier political centrality.

The most historically unexpected feature of the castle is its current occupant. Since 1930, the Polish Museum Rapperswil (Muzeum Polskie w Rapperswilu) has occupied the castle building — a museum dedicated to Polish history, culture, and the Polish diaspora experience in exile. The museum's origins trace to 1870, when Count Władysław Plater, a Polish political exile, established an archive and collection in Rapperswil documenting Polish history and the experience of the successive Polish diaspora communities that had settled in Switzerland. Rapperswil's connection to Polish exile culture runs through the 19th and 20th centuries: Polish political exiles from the failed uprisings of 1830 and 1863 against Russian and Prussian partition settled in Western Europe, with a significant community around Rapperswil and Zurich; the Solidarity-era emigration of the 1980s added further layers. The collection documents this diaspora history alongside the broader history of Poland through art, archives, and material culture — an institution whose existence in a Swiss lake castle is genuinely unexpected and whose specific holdings are of serious interest to anyone engaged with Polish cultural history.

The town of Rapperswil is designated the Rose City (Rosenstadt) for its extensive rose gardens — approximately 15,000 plants in 600 varieties planted on terraces below and around the castle, descending toward the lake promenade. The combination of the castle on the hill, the rose terraces, and the Lake Zurich view across the narrows has been the defining image of Rapperswil in Swiss tourism since the 19th century, and the gardens are at their most spectacular in June and July.

The GYG product linked on this page (t882066) is a 9-hour day trip from Zurich branded around three stops — Rapperswil, Einsiedeln monastery, and the Lindt Home of Chocolate museum — in which Rapperswil is the first sightseeing stop. This is not a Rapperswil-focused guided castle tour; the tour's emphasis and marketing is primarily around the chocolate museum. The €134 price covers all three stops in private group format. Disclosed plainly because visitors specifically seeking the castle and museum should know the GYG tour's character before booking. Independent visitors can reach Rapperswil from Zurich by S7 S-Bahn in 40 minutes — the most flexible option, allowing time in the rose garden, castle museum, and on the wooden bridge at your own pace.
