A few days ago, we visited Suwon Hwaseong Fortress, Korea. Its walls are almost six kilometers long. They are interspersed with towers and various wooden structures. Suwon Hwaseong Fortress is a World Heritage Site. It looks like a miniature Wall of China.
Walking on Hwaseong Fortress, I recalled a few walls that man has been building over time: the mighty walls of Troy, the walls of Rome erected by Emperor Aurelian to protect the city from barbarian invasions, the Hadrian’s Wall that marked the boundary between the Roman Province of Britannia and Caledonia, and many other walls.

Besides the walls made of bricks, man has been building immaterial walls. The most notorious is the Iron Curtain, an invisible wall that divided the world into two parts, during the Cold War. Even the borders between nations are invisible walls.
Will man be able to demolish these walls someday? The most difficult walls to eliminate are those that surround our hearts. Even unknowingly, every day we build walls around our hearts to protect ourselves from others. If we are able to remove the walls in our hearts, those between nations will also collapse someday!
