A fresco is a painting made directly on wet plaster, usually on a wall or ceiling. The artist works quickly because once the plaster dries, the paint becomes permanently part of the wall itself. The word comes from Italian and means “fresh,” referring to that wet plaster.

Fresco painting requires careful planning and confidence. Artists can't easily fix mistakes because the plaster dries within hours. They often work in sections, applying fresh plaster to only the area they can paint that day. Michelangelo used this technique for the famous ceiling of the Sistine Chapel in Rome, spending years on scaffolding as he painted scenes from the Bible.

The technique produces remarkably durable artwork. Many frescoes created over 500 years ago still look vibrant today because the paint chemically bonds with the plaster as it dries. Renaissance artists in Italy perfected fresco painting, covering church walls and palace ceilings with massive scenes of historical events, religious stories, and mythological tales.

You might see frescoes in museums, old churches, or historic buildings. Unlike paintings on canvas that you can move around, a fresco stays where the artist created it, becoming a permanent part of the architecture itself.
