We received a tip about a massive wall that looks just like a fortress wall! In fact, we were able to confirm its existence on a secluded mountain path behind the road..! With more than 10 pillars supporting the retaining wall alone, it stands approximately 23 meters tall, a massive structure the size of an 8-story apartment building. Its scale and size were so overwhelming that they made even a person look like a miniature..! Why on earth is such a massive retaining wall located here? Given that this is a landslide-prone area, we wondered if it might be a landslide prevention structure. While continuing our investigation, we received a tip that the railway tracks next to the retaining wall are still in use. Do they know the true nature of the retaining wall? We visited the business in question to verify... only to discover the shocking fact that there isn't just one such wall! 'SBS Wide' investigates exactly what purpose this retaining wall was built for and what its true identity is. SBS 'Morning Wide Part 3' 'Mr. Reboot' (Aired Feb. 14, 2025)
