The Brigada Ramona Parra transformed Santiago's walls into a disciplined visual language of resistance — thick black outlines, flat primary colors, and stencil-cut slogans painted in three-night cycles during Allende's Popular Unity government. After the 1973 coup erased their murals and scattered their members, the BRP aesthetic survived underground, resurfacing in the late 1980s and exploding again during the 2019 estallido social — proving it remains a living tradition, not nostalgia.
