In very close proximity to the Swiss Federal Institute of Technology (ETH), the University and Zurich University Hospital, a science park for life science companies and institutions has developed in the last two decades, which has acquired both national and international significance. Based in and around what was once the site of the industrial firm Schweizerische Wagons- und Aufzügefabrik AG, with a base area of 55,000 m2, the park now hosts more than 50 companies, and 25 academic research centers representing a healthy mix of young start-ups and global companies as well as universities.
