Historical Overview

Military Origins and Transformation

The Old Botanical Garden occupies a hill that once formed part of Zurich’s Baroque city defenses. The Katz bulwark (1648–1664) featured thick stone walls and underground casemates, serving as a strategic vantage point for city defenders (hellozurich.ch). Visible remnants of these fortifications can be seen along the Schanzengrabenpromenade, connecting the garden’s landscape to Zurich’s martial past.

With the decline of military threats, the bulwark was gradually dismantled from 1835, making way for a new purpose. In 1833, alongside the founding of the University of Zurich, the site was transformed into a botanical garden under the guidance of Johannes Gessner and the Zurich Natural Science Society (uzhfoundation.ch). This transformation mirrored a wider European movement of turning military structures into public green spaces (myswitzerland.com).

Architectural and Botanical Highlights

The Palm House (Palmenhaus)

A centerpiece of the garden, the octagonal Palm House was inaugurated in 1851 and reinforced with a cast-iron frame in 1877 (bg.uzh.ch; Wikipedia). Originally home to exotic plant collections, it now serves as a protected monument and vibrant cultural venue for concerts, theater, and exhibitions. Note: The Palm House is open from May to September and closed in the colder months (bg.uzh.ch).

Gessner Garden (Gessner-Garten)

At the highest point of the grounds, the Gessner Garden pays tribute to Conrad Gessner (1516–1565), a pivotal figure in natural science (bg.uzh.ch). This medieval-style herb garden features over 50 medicinal plants, with informative signage on their historical uses, providing a living lesson in Zurich’s scientific and botanical heritage (zuerich.com).

Arboretum and Historic Trees

Mature trees, some planted in the 19th century, create a lush canopy and tranquil setting. The arboretum, while compact, offers a diverse range of species, contributing to the garden’s timeless atmosphere and making it a favorite spot for leisurely strolls (triphobo.com).

Ethnological Museum (Völkerkundemuseum)

Located within the garden, the University of Zurich’s Ethnological Museum (Völkerkundemuseum) features rotating exhibitions on global cultures (lovinswitzerland.com). Entry is free, though the museum is closed on Mondays.

Remnants of Baroque Fortifications

The garden’s raised topography and Schanzengraben moat are direct legacies of the Katz bulwark, offering visitors a tangible link to Zurich’s military history (Wikipedia).

The Garden’s Academic and Public Role

From 1833 to 1976, the Old Botanical Garden served as the University of Zurich’s main center for botanical study and research (uzhfoundation.ch). After the main collections moved to a new site in Riesbach in 1977, the garden transitioned into a beloved public park, maintaining its educational mission through guided tours, workshops, and cultural events (bg.uzh.ch).
