Ready for storm season
The annual test closing marks that Rijkswaterstaat is ready for the coming storm season. The Europoort barrier protects 1,5 million inhabitants of Rotterdam and the surrounding area from storm floods of the North Sea. The test closing is meant to show possible technical or operational problems, so these can be worked out before the storm season starts (October 1st – April 15th).

Saturday September 17th 2016 Maeslant storm surge barrier and Hartel barrier (together named Europoort barrier) close their gates during the annual test closing. The Keringhuis is open for visitors the whole day and organizes tours of the site and various activities for children. The start of the test closing is expected at 15:00. The time can still change under the influence of natural circumstances. The test closing is a public event.
