Stone Sport

The outer work

A week of dry stone walling in the Alentejo, with Steven McKay.

Nothing holds a dry stone wall up but gravity and judgement. Eight people, every level welcome, and your stay, breakfast and lunch included.

Next weeks: Mar 2027 and Apr 2027

Stone Sport keeps the craft of dry stone walling alive by passing it on, and gives people time away from busy city life, in the quiet of the Portuguese countryside. It is the outer work of Nature's Portal, the non-profit association that cares for the land.

Everyone is welcome, from people who have never laid a stone to professional stonemasons. You need to be happy on your feet outdoors and not mind making mistakes in front of other people.

The group works like a company of actors getting ready for a play. Everyone has a part, and the parts can change.

  1. Breakfast together

    The day starts at the table at eight. Everyone sits together and talks about the work ahead.

  2. One team on the wall

    Each person takes a part that suits what they can do, what they would like to do, and what they want to learn from the week. Over the days you see who is good at what. When the work changes, the parts change with it.

  3. Lunch in the shade

    Lunch is eaten together, in the shade nearest the wall. Tools go down after it, at about two.

  4. The afternoon is yours

    Work starts early and stops before the heat. The rest of the day is free.

The times are approximate.

The Walling Week: one course, run twice, in spring before the heat. Mornings on the wall with Steven, afternoons your own.

Everything about the course

Builders coursing stone into a new retaining wall

What you build on a walling week is not a practice wall. Every wall is a real project on Nature's Portal, the land the courses belong to.

A wall here shelters an olive tree, holds water in the ground, or gives frogs, lizards and birds a home. And what the courses bring in goes back into the land as well. These are the projects that need walls:

Cross-section through a dry stone wallA dry stone wall cut through its width. Foundation stones sit in a trench below ground level. Above them two faces of coursed stone lean inward as they rise, with small stone packed tight between them. Two long throughstones reach the full width to tie the faces together, and coping stones set on edge finish the top. 123456
A wall cut through its width, drawn to the rules it is built by: the joints break and the faces lean.

A dry stone wall stands because every stone does a job for the stones around it, and it comes down when one of them stops. These six are the whole syllabus. Learning them well takes about a lifetime.

  1. Foundation

    Dug down through topsoil onto ground that will not move, and set a little wider than the wall it carries. The heaviest stones in the whole job go in here, below the line, and nobody ever sees them again.

  2. Coursing

    Stones go in long into the wall rather than along it, and every joint is covered by the stone above: one over two, two over one. Get that wrong in the first hour and the wall will tell on you for a century.

  3. Hearting

    The middle is packed by hand with small stone, each piece wedged against its neighbours. It is placed, never shovelled. Loose hearting is the commonest reason a wall bellies out and comes down.

  4. Batter

    Both faces lean in as the wall rises, so the two halves lean on each other instead of away. The dashed lines are plumb. Everything you build sits inside them.

  5. Throughstones

    Long stones set at intervals that reach right across and bear on both faces, tying what would otherwise be two thin walls into one thick one.

  6. Copes

    Set on edge along the head, packed tight and oversailing a little each side. They press the courses below together, throw the rain clear of the hearting, and stop anything with hooves picking the top apart.

Steven McKay on site with two young builders, red earth cut behind them

The weeks are taught by Steven McKay, a stonemason who has worked with stone his whole life. He learned the trade in Scotland, built houses for his family and children over the years, and is now building on his own land in the Alentejo. The stone there is schist and the earth is the colour of rust, but the craft is the same.

Steven teaches every week himself, and the group is kept to eight at most so that he can watch what each person's hands are doing. You work on real walls, not a practice wall in a yard.

The saltwater pool in the valley at Monte Maravilhas, among olive and orange trees

You stay at Monte Maravilhas, a small estate of houses on a hillside near the village of São Martinho das Amoreiras, with a saltwater pool and the Rota Vicentina walking trail passing by. Breakfast and lunch are made for you every day.

Work finishes after lunch. The afternoons are for the pool, a walk, a swim at Santa Clara lake or a long sleep. In the evening you find your own dinner, and we give you a list of good places nearby.

Come and build with us

There are eight places in each week. If neither March nor April suits you, tell us and we will let you know when the next dates are set.
