Doors Open Day (Open Bedrijvendag) is a yearly Belgian event during the first weekend of October. Belgian companies open their doors to the public. And so does Jan De Nul coming Sunday, 2 October 2022.

During the day, you get the unique opportunity to take a look behind the scenes at Jan De Nul in Aalst. A family business in heart and soul, a major world player. Behind the office building in Aalst lies an even bigger site with warehouses, workshops and garages to supply sites and vessels worldwide. Visit the workshops and at the same time make a journey through the world of Jan De Nul. Fascinating for young and old.

Fancy a new challenge? During Doors Open Day you get the chance to meet the people behind this company. You might even find your dream job! We are looking forward to meeting you.


Don't forget to register for the visit. The visit is completely free and you can choose out of different time slots. The visit is about 1 kilometre long and fully accessible for wheelchair users. A visit lasts between 60 and 90 minutes. 

To optimise the flow of visitors, we ask you to register at least 15 minutes before the start of your chosen time slot. Fifteen minutes after the start of your time slot, we will close your group until the visitors of the next time slot present themselves.


Parking attendants will direct you to the right car park.
