Camillo Sitte and the Case for Complexity: Why Your Brain Prefers Winding Streets Over Wide Open Nothingness

There’s a strange little thing that happens when you walk through certain places. You turn a corner. You stop. You linger. Not because the signage tells you to. But because the space invites you. Makes you curious to explore.

It’s not the café. It’s not the cathedral. It’s the composition. Another example is the small moselle town of Remich here in Luxembourg: The old centre has small little openings and winding tiny footpaths between houses. They pique your interest, you feel the impulse to explore and find out where the path leads. Irresistible.

Camillo Sitte (1843 - 1903), the Austrian urban planner with more common sense than most modern zoning boards combined, understood that.

Back in 1889, he wrote “Der Städtebau nach seinen künstlerischen Grundsätzen” (“City Building According to its Artistic Fundamentals”) and argued, quite radically, for his time, that cities should be designed like art, not spreadsheets.

Today, you wouldn’t know it.

Walk through most new developments in Luxembourg (or anywhere else where the planning software and developers get more say than the people).

What do you see?

Vast spaces. Flat façades. Identikit balconies, doors and garages. Colours mostly white and grey. A tragic excess of “rational layout.” It’s not offensive. But it’s not beautiful either. It’s just... there.

And as Sitte might have said: beauty rarely comes from “just there.”

Aesthetic Undercomplexity - Or Why Bland Hurts

Sitte didn’t use the phrase “ästhetische Unterkomplexität” himself, that came later, but he would’ve nodded in grim agreement and everything he wrote was a rejection of it.

He believed that when we strip cities of visual richness, variation, and spatial rhythm, we’re not simplifying, we’re impoverishing.

The plazas and streets he admired weren’t efficient. They were emotionally intelligent.

Irregular. Enclosed. Multi-perspectival. They played with light, surprise, and scale. They created places where people actually wanted to pause. To stay. To belong.

That's why his body of work speaks to me. I lived in quite a few places, and the ones which stuck in my mind and still fill me with longing sometimes, are the ones with aesthetic layering, with delicious visual complexity. They hold your attention in a curious way, they give your mind space to think while anchored by buildings, like for instance, the Heath in Blackheath Village, London.

The village for intimacy, cosiness, human scale, and the heath to expand your mind. All within a bustling city. I believe, you know that a place works when you live there for years and years and still it touches and delights you. 

Compare that to today’s planning: functional rectangles with generous parking and zero soul.

Further, mixed use according to a PAG in Luxembourg also often means in practice: the bakery and the yoga studio share a concrete wall in a building that looks like a converted insurance office. Interspersed with Bauhaus style bland residences. People come and go, but no one ever stays.

The Science Backs Him Up

Modern neuroscience research agrees with Sitte. Our brains are wired to respond to complexity, not chaos, but structured variation.

Environments with texture, depth, and contrast stimulate cognitive activity and emotional well-being. Flatness, uniformity, repetition? That’s how you drain a person’s spirit without saying a word.

No wonder people flee the village core the moment it’s filled with new “units.” The rhythm is gone. The charm evaporates. And nobody wants to live inside an Excel file.

From Vienna to the PAG

It’s curious, really. Sitte was writing in Vienna, a city that still carries layers of old urban intelligence in its bones. But his insights land sharply here in Luxembourg, too - especially in how village centres are being “densified.”

I look out from my own house and see what’s coming. Not bad intentions. Just bad proportions. The idea that function alone is enough to create place.

But we know better.

We’ve walked the streets that work. The ones that hold you, soften you, surprise you. They’re not accidents. They’re compositions. Spatial symphonies. And Sitte understood that and could compose the music.

Final Thought: Complexity Is Not a Flaw

We don’t need more diagrams. We don’t need more Bauhaus architecture. We need more delight.

Camillo Sitte knew that beauty wasn’t a luxury. It was the organising principle. Without it, cities may function, but they will never sing.

And honestly, when was the last time a zoning plan gave you goosebumps?
