Almost as soon as you turn onto Protestant Shankill Road, you pass a building that has been entirely painted with the Union Jack flag. A few blocks down the road, and off to the right, you'll see a cluster of enormous murals, including one celebrating Oliver Cromwell, who massacred Irish Catholics in an effort to conquer the island. Shankill is indefinably grimmer than the Falls Road -- it's more down at heel and you'll see more boarded-up shops, but the people are generally friendly. Shankill murals seem to be darker than those on the Falls, where many murals are about solidarity with the downtrodden; here, they're all about the corruption of Catholics, with a display of painted weaponry, although some of the more aggressive murals were removed in 2010.
