My project is an outdoor climbing center. This idea comes from my experience in climbing. In this center, there are three top-roping routes and a bouldering wall. One of the four walls has a pulley system for the safety of the climber. The colors on the holds represent the level of difficulty of climbing. Blue is the easiest color, yellow is medium, red is difficult and white is for the pros only! Underneath the hut you will find all the equipment including a chalk powder pot. On the ground, there are mats to cushion the climber's fall. I hope you enjoyed this LEGO.
