A fresco is a technique of mural painting that involves applying water-based pigments onto freshly laid wet plaster. As the plaster dries, the colors bond with the wall, creating a durable and vibrant artwork. This method has been used since ancient times, particularly in Renaissance art, where it was popularized by artists like Michelangelo and Raphael. Frescoes are often found in public buildings, churches, and palaces, showcasing religious themes or historical events. The technique requires skill and speed, as artists must work quickly before the plaster dries. Frescoes can be seen in famous locations, such as the Sistine Chapel in Vatican City.
