Bock Beer Borrel

Dear Gyrini,

The sunny summer days are slowly being replaced by the rainy autumn days. The nights will be longer, and the days will be shorter. The t-shirts will be replaced by coats. The wind is very cold. Once you arrive home you put on your comfy outfit and take a seat at the warm fireplace. Nana’s famous stew has been simmering on the stove all day. Staring through the window watching the leaves fall of the trees you think: “aahhh autumn.” What is missing on a night like this? Exactly, a collection of the most delicious bock beers. Autumn is coming and so is the Bock Beer Borrel on Friday the 25th of October at de Tegenstelling! We open our doors to give you a warm welcome and provide you with the best season bound bock beers!

Vondelpark clean-up

Dear Gyrini,

The Actcie is back with the second edition of the Vondelpark Clean-Up on the 17th of September! Whats a better way to start this school year than help creating a less polluted environment. Of course, only cleaning up the Vondelpark doesn’t solve the current issues regarding our polluted environment, but at least doing something is better than doing nothing.

Do YOU want to help us by picking up trash and putting it where it belongs, don’t hesitate any longer and sign up! Scared you are going to get dirty? Don’t worry! We will be wearing jackets and will use pickers (afvalgrijpers).

Sign up by sending an email to: ln.su1571032523niryg1571032523@eict1571032523ca1571032523

First Stelling Evening

Dear newbies and veterans,

The wait is finally over. It is time to kick off the new college year at the best bar the VU could ever give to you: de Tegenstelling!
The seniors can finally drink that sweet, sweet Budels again which they have craved for this past summer. And the freshmen can finally discover what this ‘Budels’ actually is and what a real Wednesday night at Gyrinus is like.
At this First Stelling Evening you will experience the hospitality Gyrinus is known for and you will create beautiful memories which you will remember forever (or not..?).
Most of all, we want to give you a warm welcome and introduce you to your second home: Gyrinus natans!

We will see you the 4th of September in WN-D103!

Love, het Alcoholaat
