Why Dutch homes in the Netherlands keep curtains open at night

Open curtains often catch the eye of anyone walking through residential streets in the Netherlands after dark. With living rooms lit and windows left uncovered, everyday domestic life becomes partially visible from the pavement-an everyday custom shaped by religious history, neighbourly trust and social expectations around discretion.

Why do so many Dutch homes keep their windows uncovered?

In the Netherlands, leaving curtains and blinds open is not generally seen as an invitation to peer inside. The window acts as a transparent boundary: residents do not conceal the living room, yet they expect passers-by to carry on walking rather than stop to look.

You tend to notice this most in residential areas, particularly at ground level, where lamps, plants and furniture can be seen from the street. Not every household follows the practice, but it remains common enough to surprise many visitors from abroad.

What does the Calvinist tradition have to do with this habit?

One historical explanation links uncovered windows to the influence of Calvinism, which spread across the region from the 16th century onwards. In this reading, a home that could be seen into signalled honesty, discipline and the idea that the people living there had nothing improper to hide:

• Home life was expected to show order and sobriety;
• Transparency was associated with moral conduct;
• Closed windows could arouse suspicion within the community;
• The house served as a public display of organisation.

Is there an unspoken rule about not looking into people’s homes?

The custom relies on an important social counterpart: people in the street avoid staring into homes. A brief glance at a lit window may happen, but stopping outside or watching the occupants for any length of time would be considered intrusive.

That self-restraint protects privacy without the need for permanent physical barriers. In this way, open curtains coexist with a clear sense of personal limits-based less on hiding the home and more on respectful behaviour from neighbours and passers-by.

Does this habit still make sense in modern life?

Today, the reasons for keeping windows uncovered extend beyond religious tradition. Some families value daylight, a greater sense of space and visual contact with the street, while others draw the curtains only in bedrooms or at particular times. Current motivations include:

• Making better use of natural light during the day;
• Preventing rooms from feeling shut-in and gloomy;
• Keeping a visual connection with the neighbourhood;
• Letting morning light in as soon as you wake;
• Maintaining a custom passed down through generations.

How does natural light affect sleep and waking?

Morning light exposure helps the body recognise that the waking period has begun. For that reason, leaving curtains open-or opening them soon after getting up-can support the alignment of the body clock, even though the bedroom still needs to be dark enough during sleep.

The Dutch habit also points to a broader cultural relationship with transparency, discipline and collective trust, much like other everyday practices in the Netherlands. Lit windows may remain on display, but privacy is maintained through a tacit agreement: residents do not hide their home, and those outside do not cross the line with their gaze.
