Arboretum Zürich, Botanical garden and park in Zürich, Switzerland

Arboretum Zürich is a 41,360 m² park on land reclaimed from Lake Zurich during the 1883–1887 quay works. Its tree collection follows Carl Schröter's plan: nine geographic sections (southern Switzerland, the Alps, the Jura, the Mediterranean and Orient, the southern and eastern US, California, Japan, China), four systematic groups of elms, maples, ashes and beeches, and a Tertiary section on the small hill. The Bluntschli Fountain (1909) stands at the General-Guisan-Quai entrance.

The Arboretum lies on 41,360 m² of level ground reclaimed from Lake Zurich during the 1883–1887 construction of the Quaianlagen, inaugurated in 1887. In 1885, shortly before building began, botany and geology professors proposed enriching the planned conventional park; a commission including landscape architects Evariste Mertens and Otto Froebel and botanist Carl Schroeter added a tree collection, a rock collection and Zurich's first Alpine panorama. Planting design began in 1886.

The site holds the designation of class A Swiss cultural property of national significance, reflecting its role in shaping how people understand nature and gardens. Visitors experience a living example of garden culture here, where carefully maintained tree sections and thoughtful pathways teach people about tree diversity.

Visitors can reach the site using tram line 5 or bus lines 161 and 165, with stops at Rentenanstalt station. Pathways throughout the grounds accommodate different walking paces and mobility needs.

Three one-man bunkers were built in 1942 among the trees of the China group on the lake shore, intended to protect the lower lake basin; they have been under cantonal conservation since 1992. Near the Enge lido stands a beech group whose central tree was lost in 2006, leaving an open gap.
