About Faculty of Science

The Faculty of Science is located at the Leiden Bio Science Park. It was founded more than two centuries ago and currently, more than 8000 people are working and studying at the eight institutes.


The Faculty of Science is spread over various buildings. The Science Campus consists of the Gorlaeus Building, Gorlaeus Lecture Halls, Gorlaeus Faculty Office, LMUY, Huygens, Oort and Snellius. The buildings Sylvius and Van Steenis are also situated at the Bio Science Park.

The new Gorlaeus Building is in full development. In the future it will house all institutes and departments under one roof. The Gorlaeus Building offers a high-tech environment with state of the art research and education facilities. The first phase of the Gorlaeus Building has been completed and it is in use since 2016. We are currently working on the design for the second phase.

Facts and Figures

The Faculty of Science was established in 1815. Late 2022, it was home to 2298 staff members. Regularly, our staff and students receive grants, prizes, and distinctions.
