You’ll find Eindhoven’s High Tech Campus to the south of the city, just between the Dommel River and the outer motorway ring. So if you hire a car here you’ll find the road links to the rest of the city and the North Brabant area are excellent. The Campus itself is small district dedicated to more than 100 modern technology companies with shared research and development facilities, many of which once formed part of the Philips headquarters based here. The sustainable eco-site measures just a square kilometre but generates half of all the patent applications in the Netherlands. It calls itself “the smartest km2 in the Netherlands.”
