Architecture Day/Week in The Hague gives the public the opportunity to experience the interior of The Hague's unique buildings. Numerous buildings in the city that are not normally accessible will open their doors during this day.

Theme of Architecture Day 2026: in transition 2.0

How can we build homes that not only use energy, but also produce it? How can we ensure that we reuse vacant buildings and never demolish them again? How can we keep our feet dry in a wetter climate and with rising sea levels? In short, what will the Netherlands look like in the future?

It is clear that we need to use space differently in our densely built-up Netherlands. We need to change now. We are already on the move in some respects. In other words, the Netherlands is in transition...

The ideas, plans and opportunities are there, but that is only one side of the coin. How can we turn them into reality? According to Professor Jan Rotmans, we must above all overcome our fear of major change. Because that fear is holding us back. That fear will diminish if we have a clear picture of the major change and what we are facing. If we see, hear and taste how things can be different.

During Architecture Day 2026, we will show this to a wide audience and discuss it. There will be open houses at special buildings, guided tours of the city, exhibitions and lectures about our changing living environment. Will you be there?
