What is outsider art?
Outsider art is art made by self-taught people working outside the official art world of art schools, galleries and dealers. Many of its makers never called themselves artists, and much of their work was found only late in life or after they died.
The idea began in France in 1945, when the painter Jean Dubuffet coined the term art brut, "raw art", for work by psychiatric patients, mediums, prisoners and isolated people. In 1972 the British critic Roger Cardinal translated it as "outsider art".
Today the term covers everything from pen drawings on scraps of paper to whole buildings transformed by one person, and it is fiercely debated. We explain it all, and the graffiti tradition that grew up alongside it on Britain's walls.

Art you can walk into
Visionary environments
Some outsider art is too big for a wall. A visionary environment is a home, garden or plot of land transformed, usually by one person over many years, into a single work of art, often from stones, broken crockery and cement.
They are among the most fragile kinds of art. Many have been demolished; the survivors often owe everything to campaigners.

What is the difference between art brut and outsider art?

Compare the terms.
