The Colinton Tunnel in Edinburgh is home to Scotland's largest historical mural, brightening up a once dark and scary railway tunnel. Created by a talented art team led by Chris Rutterford, the mural celebrates the industrial, social, artistic, and literary history of Colinton's community. Visitors can enjoy this enchanting artwork while strolling through the tunnel, making it a must-see spot for those looking to explore the area. Donations are welcome to help maintain the mural's vibrancy and keep the tunnel a welcoming place for all.
