Muralists from across the globe are transforming walls into wonders full of creativity, imagination, and opportunities to connect. The joy of wall murals is contagious. Pops of art — on brick walls, freeways, and street corners — brighten our routines and remind us that the world is full of wonder, surprise, and opportunities to look up when we’re all too often looking down. But wall murals do even more than provide something nice to admire. They are also shown to have some serious benefits, ranging from uniting diverse communities, sharing messages for social change, improving mental health, and increasing tourism and safety.
