“Heaven la earth hammock” in the heart of Stockholm, Sweden

At the end of the 19th century, shortly after man patented the first telephone, the race to connect people and telephone grids followed. However, due to technical and design limitations, all human telephones at the time required separate physical lines. These wires are interconnected through homes or businesses with a telephone exchange, where calls are manually connected. As a result, people had to build odd-looking towers for the purpose of connecting telephone wires, but this tower could carry hundreds to thousands of phone lines depending on its size.
