'You'll be able to tell your grandchildren later that you were the first students to be taught in Orion,' jokes ecology lecturer Elmer Veenendaal on Monday morning, 6 May.
Underneath the lecture hall is the canteen and the 'largest student bar in Wageningen'. Orion has its own caterer, OSP. You can also get Chinese takeaways, just like in Forum.
Orion is slightly taller than Forum, 48 metres compared with 44 metres. Orion is the third monolith to appear on campus after Atlas (2006) and Forum (2007). The fourth Helix for food scientists is scheduled for 2015.
