Hortus Botanicus Lovaniensis

Hortus Botanicus Lovaniensis is a historic botanical garden right in the heart of Leuven, Belgium, and one of the oldest gardens of its kind in the country. Its story goes back to 1738, when Henri-Joseph Rega, a professor of medicine at the University of Leuven, founded the first garden on this site to grow medicinal herbs for the medical practice of the time. Over the following decades the garden expanded beyond its original purpose, developing into a place of study that held an extensive collection of ornamental plants, economically useful species, and rare specimens used for teaching and research.

How has the garden changed over the centuries?

The fortunes of the garden were closely tied to those of the university itself. When the university was shut down in 1797, the garden was seized by the state. A new chapter began in the 1820s, when a fresh botanical garden was established next to the original site, this time under the newly founded State University of Leuven. That university, in turn, closed its doors in 1835, after which ownership of the garden passed to the city authorities. The very first site from 1738 did not survive intact — in 1874 a girls' school was built over it. The garden created a few decades later, however, remained in place and continues to this day as a municipal park.

What can visitors see in Hortus Botanicus Lovaniensis today?

Today the garden covers 2.2 hectares and sits right in the city centre, making it easy to reach for residents and visitors alike. Entry is free, which helps explain why it is so widely used on a daily basis — for a walk, a quiet break, or a short pause between sightseeing stops elsewhere in Leuven. In many ways the garden now works as a green pocket within the dense historic core of the city, combining its academic and historical roots with a clear role as an everyday recreational space open to everyone.

It is also worth noting that the garden's role is not purely botanical. The grounds are occasionally used as a venue for exhibitions of contemporary art, adding a cultural layer on top of the historical one. Visitors strolling among the plantings may therefore come across art installations or displays set within the framework of what was once a university teaching garden.
