About Ufenau#
Ufenau is the largest island in Lake Zurich, located near Rapperswil-Jona in the canton of St. Gallen, Switzerland. The island is noted for its early medieval church buildings and for being a protected natural area on the lake.
Visitors find a compact site combining built heritage and natural landscape: two historic churches and ruins stand near walking paths through wooded areas and shoreline. The island is used for short visits, picnics and birdwatching rather than extended stays.
Historically the island has strong monastic links and was tied to the Einsiedeln Abbey in the Middle Ages; the churches date from the early medieval period and have been preserved as part of the island’s cultural heritage.
