The fake tree that became the secret weapon of the Periscope Tree: When the tree became the hidden eye on the front lines of World War I, the Western Front was filled with cruelty and danger, soldiers faced an unexpected attack from the front lines, and just the head from the fire pit could mean sudden death amidst this darkness and a broken heart, an innovation called the "Periscope Tree" or the spice tree was considered to have given birth to a new hope for British soldiers.The Periscope Tree is not a typical tree, but it is a visual remote viewer hidden in a wooden trench and a tight steel structure. This tree provides security for soldiers stationed inside because it can track enemy movements without coming out exposed. The traditional design that mimics real trees and the staircase concealed with a specific enclosure allows the owner of the area on the edge to have a line of sight even in the dark or in the dangerous area. The historical record shows that the Periscope Tree has played a key role in collecting strategic intelligence, information that has helped to plan accurately and to build the battlefields.The detailed images of the spice tree show the commitment of soldiers and builders who combine engineering and art together, not only as tools but also as a symbol of ingenuity and skillful living amidst the atrocities of the Periscope Tree war.
