Water mills, from the Bugio to Freixieiro
Around here the mills you can visit are water mills. It was the river that ground the grain, sawed the timber and even distilled the brandy.
Facts researched from public sources. Check opening hours and contact details before you go.How a water mill works
- A weir diverts part of the river’s water.
- A mill race carries it to the mill.
- Water falls onto the blades of a wheel and the wheel turns the upper millstone over the lower one.
- The grain falls between the two millstones and flour comes out.
There are two common kinds of wheel: the vertical azenha and the horizontal rodízio. The rodízio, simpler because it needs no gears, was the commonest on the rivers of the North.
A study of mill records from the neighbouring Ave valley shows what it was like: more than 80% were for private use, almost 80% ground cereal and horizontal wheels far outnumbered vertical ones. Many fell into ruin after the 1960s, when industrial and electric mills took over the work.
A miller’s words
Weir
It diverts water from the river into the mill race.
Mill race
It carries water from the weir to the mill.
Rodízio (horizontal wheel)
It has blades and turns when the water hits it. It needs no gears.
Azenha (vertical wheel)
A wheel that turns vertically, pushed by the water.
Millstone
Every mill has two, one on top of the other. The upper one is the one that turns.
Pejadouro
It opens and closes so the miller can regulate the water.
Argontim, on the Bugio river
In Argontim, in the parish of Rego, the Bugio river feeds the mill races and the wheels of mills, a sawmill and a still. Many mills date from the Middle Ages or earlier: they ground grain, the sawmill worked timber and the still made brandy. The water was managed in common by the communities.
The Lameira Plateau Museum Centre occupies the sawmill. It shows restored hydraulic structures that work with the original systems, and an archaeology exhibition from Prehistory to Roman times. The route passes the restored mills and ends in a leisure area by the river.
A September 2024 account counted ten mills along the route, among them one that pressed olives and a large sawmill with two vertical wheels. It also said the museum centre was closed and that some paths were overgrown, with works planned. to be confirmed So call the Tourist Office before you go.
Freixieiro park
In the middle of town, Freixieiro park follows the river of the same name. It has restored mills on its banks, waterfalls and, next to the campsite, a bathing area that works in summer, with a shaded sandy beach.
You can see it all on foot, slowly, in an afternoon.
Before you go
- Call the Tourist Office before going to Argontim.
- Some paths along the river may be overgrown.
- Freixieiro is easier: it’s in the middle of town.
- The Freixieiro bathing area only works in summer.
- Wear shoes with grip: wet stone is slippery.
