That horrible sound you heard today? It’s the monthly siren test. It’s there for your safety but I can imagine, if you just got in Groningen, it’s a terrifying sound. Well, don’t be scared though! Every first Monday of the month the siren will go off at around noon. The control room in Drachten is just testing whether the siren still works properly. Because if a disaster happens, you must be able to hear the siren clearly. The test takes about a minute and a half.
Will they cancel the test anytime. Well yes, the siren won’t be tested on the first Monday of the month when there’s a public holiday or anything like a Remembrance Day on Mondays!
