There is one photograph everyone brings back from Provence: a line of dark, narrow cypresses set against a field. It reads as decoration, a postcard detail. It is the opposite. It is a structure built to resist a specific wind, and its position on the ground is not a free choice.
01 The cypress rows are a piece of engineering
The cypress prevailed here for two practical reasons: it grows fast and it keeps its leaves, so it protects in winter too, which is when the mistral bites hardest. Across the farming plains of the Vaucluse and the lower Rhône it was planted as a network, row after row, until it formed a continuous fabric of barriers.
The placement follows a simple rule: the tall hedges are set perpendicular to the valley axis, that is, across the path the wind takes. So the moment you identify the direction of the tree lines, you know where the wind comes from. The landscape wears its own compass.
Where the crop is more delicate, the barrier changes material. In the Comtat Venaissin, reed screens and hedges of young cypress are used as well, lower and denser, planted beside the market-garden plots that would not survive a direct gust.
02 What a hedge protects is not only the plant
The barrier does more than slow the air. By reducing ventilation over the plot, it raises the heat accumulated across the year and creates a measurable microclimate behind the tree line. That small thermal head start is what gives the Comtat's market gardens their reputation for earliness.
The cypress row does not decorate the field. It gives it a few degrees and a few days.
03 The old house turns its back on the north
The same logic governs the mas, the Provençal farmhouse. It faces south, and the north side is left essentially blind: no openings, or only the strictly necessary. Bedrooms look to the midday sun, and a corridor typically runs along the north side, acting as a buffer between the wind and the rooms.
On the remaining facades the windows are narrow for the same twofold reason: keep out the summer heat, keep out the winter cold. An old Provençal house is dark inside, and that is not a period flaw: it is the intended result.
04 The cornice counts the floors
Under the roof there is a detail that can be read precisely. It is called a génoise: an eaves course made of overlapping rows of curved tiles that projects beyond the facade, works as a gutter and throws the water clear of the wall.
What is interesting is that the number of courses is not arbitrary. The traditional convention is that the génoise carries as many rows of tiles as the house has levels. Counting the courses from the street is, literally, counting the floors of the building without going in.
05 How to read it from the road
- Look for the tree lines firstIf they are long, straight and parallel to each other, they mark the perpendicular to the prevailing wind. The side of the field behind them is the sheltered one.30 seconds
- See which facade has no windowsOn old houses, the face with no openings or only minimal ones is usually the north. It is the fastest way to orient yourself in a village without a map.free
- Count the eaves coursesA two-course génoise announces two levels; three courses, three. It works across most inland old towns.from the pavement
None of this requires entering a museum or buying a ticket. It is visible from a car window, from the regional train and from any village viewpoint. It is the layer of the landscape that most people photograph without seeing.
And it explains something that puzzles new arrivals: why, in a region of constant light, the old houses look closed in and the fields look compartmentalised. They were not after the view. They were after the shelter.
