Enea Tree Museum, Open-air tree museum in Rapperswil-Jona, Switzerland.

The Enea Tree Museum is a 75,000 m² park near Lake Zurich in Rapperswil-Jona, Canton of St. Gallen. It displays over 50 trees from more than 25 species, including Japanese maples, ginkgos and giant sequoias, alongside sculptures by international artists. An avenue of swamp cypresses forms the entrance.

Swiss landscape architect Enzo Enea founded this museum in 2010, motivated by a mission to save trees threatened by construction across Switzerland. This rescue purpose shaped the collection and remains central to the museum's work today.

International artists have created sculptures and installations scattered throughout the grounds, blending artistic expression with the natural setting. Visitors encounter these works while walking among the trees, making art and nature part of the same experience.

The grounds are open from March through October on weekdays and weekends, with varying hours depending on the day. Wear comfortable walking shoes as the terrain involves traversing paths across expansive space with some elevation changes.

The swamp cypress avenue at the entrance was planted before construction to drain the former wetland: the species draws large amounts of water from the soil through evapotranspiration. Many specimens in the collection were saved from felling elsewhere and replanted here by Enzo Enea.
