π

The name

The name Fundação PI carries three layers of meaning. In mathematics, pi relates a circle to its own measure, a constant without end. The circle is among the oldest symbols of wholeness: metaphysically it stands for unity, socially for the gathering of equals around a shared center. In Portuguese, PI abbreviates “Porque Importa,” because it matters, naming the foundation's reason for acting before any strategy does.

What this is

A right you cannot use is only a promise. We build the ground it stands on.
Padrão dos Descobrimentos, Belém

Recognition on paper is worth something. A door that locks, a wage that arrives, a witness who can still be found two years later — those are worth more. The Pi Foundation works on the second list.

The spiral is how we organise ourselves. Seven turns, each resting on the one under it, each with people answerable for it. Nobody is dropped in at the top, and nobody is left at the bottom.

Turn six shows the other side: seven places in Portugal, held by the people who use them. The map is public because a register only anyone can read is a register that survives the next council.

The seven layers

Programme outline · 2026–2029
Stage 1
Founders
Who began this
The raised flag marks the point of beginning: the people who first gathered around the idea, signed its charter and accepted public responsibility for its course.
Stage 2
Foundation
Form & funding
Two steady lines represent the structure beneath the work: its legal form, shared governance, sources of funding and accounts open to every member.
Stage 3
Human rights
Mandate & scope
The equal cross holds every direction in balance. It stands for universal dignity, careful casework and the limits that keep our human-rights mandate accountable.
Stage 4
Participation
Routes in
Three equal circles meet without hierarchy. They represent people joining through volunteering, membership or residency, each route distinct and equally valued.
Stage 5
Research
Studies & evidence
The open lens turns observation into evidence. It represents field studies, carefully held testimony, transparent methods and a record others can examine.
Stage 6
Projects
Work on the ground
The divided square joins place with practice. It represents active projects and the community-held sites across Portugal where the foundation’s work takes physical form.
Stage 7
Levels
Membership levels
The ascending steps show a path of growing commitment, from following the work to carrying responsibility and voting in the assembly.

Almada · across the river

Arms open across the water, facing the city that has to answer for it.

A monument is only a promise in stone. The work is whether anyone keeps it.

Together · the circle

A circle has no head of the table. Everyone in it can be seen.

Every turn of the spiral begins the same way: people standing close enough to hold each other in view, and answerable to the ones beside them.

The places

One house and its land in Memento da Beira, with more to follow.
The site is held in a community land trust and run by the people living and working on it. Titles, terms and yearly accounts sit in the open register. The map is the way in.
