What are the four categories of public art?

The four categories of public art typically include murals, sculptures, installations, and performance art. Murals are large-scale paintings on walls or buildings, while sculptures can be freestanding or integrated into landscapes. Installations often involve three-dimensional arrangements that engage the viewer in a specific space, and performance art includes live acts that may occur in public spaces. Together, these categories contribute to the cultural and aesthetic experience of urban environments.
