Hortus botanicus Leiden

Hidden behind the Academy Building on the Rapenburg lies the oldest botanical garden of the Netherlands and one of the oldest gardens in the world. Founded in 1590 and expanded in the following centuries, the Hortus is the green heart of Leiden.

The Hortus botanicus Leiden is the perfect place to connect scientists and their research with the public. Located in the heart of Leiden, our historic site attracts over 250,000 visitors annually, from a variety of backgrounds including children, students, families, and the elderly.

Focus on scientific research, education, and outreach

As a botanical garden, the Hortus focuses on three main pillars:

• Scientific Research
• Education
• Outreach

Over time, the research at the Hortus has evolved. What began as a focus on taxonomy and medical use has expanded to include a wide array of projects on plant evolution, ethnobotany, and societal issues. These research initiatives are often conducted in collaboration with a broad network of partners, both within the university (such as IBL and CML) and beyond (e.g., BLWG and Naturalis).

Citizen science projects with impact

Our citizen science projects have captured the interest of visitors and have had a tangible impact on the policies of the municipality of Leiden. This highlights the direct connection between the garden’s research and the local community.

Promoting a sustainable future

At the Hortus, we have both the space and the resources to engage our visitors in learning about a sustainable future. We have developed multiple ways to reach diverse groups, whether by visiting schools and neighborhoods or organizing activities for both children and adults.

Bringing science close to the public

Our research projects often take place directly within the garden, allowing visitors to engage with the science happening right before their eyes. Experimental setups are visible in the garden, and the results of past studies are shared with the public through outreach and exhibitions.
