Compared to the bright International Wall, the Peace Wall in the area between Westside Falls and Shankill Road is obviously bleak, and there are few other pedestrians on the street except tourists. These six-seven-meter-high, 15-million-high walls were used to isolate Catholic and Protestant settlements, and were the most conflicting places in Belfast in The Troubles. After the peace agreement reached at the end of the last century, the smoke was exhausted and calmed down. Just like the Berlin Wall, people began to express different values and pray for peace through graffiti. Looking at these guns, soldiers, and peace pigeons, we will have more personal thinking about wars and peace, which seem to be far from the long-standing human major propositions. However, according to the plan of the Northern Ireland authorities, around 2023, the Peace Wall will also face the same fate of the Berlin Wall - it was dismantled. So, its still early to go!
