In the late 19th century, shortly after the patent of the telephone, the race was on to connect everyone to the phone grid. However, due to technical limitations of the earliest phone lines, every telephone required its own physical line strung between a house or business to a phone exchange where the call was manually connected by a live operator. The somewhat quixotic result of so many individual lines was the construction of elaborate and unsightly towers that carried hundreds to thousands of phone lines through the air. In Stockholm, Sweden, the central telephone exchange was the Telefontornet, a giant tower designed around 1890 that connected some 5,000 lines which sprawled in every direction across the city. Just by looking at historical photos it’s easy to recognize the absurdity and danger of the whole endeavor, especially during the winter months. Everything that could possibly go wrong did. From high winds to ice storms and fires, the network was extremely vulnerable to the elements. Luckily, phone networks evolved so rapidly that by 1913 the Telefontornet was completely decommissioned in favor of much simpler technology. The remaining shell stood as a landmark until it too caught fire in 1953 and was torn down. If you want to see more, the Tekniska Museet (the Museum of Technology) in Stochkholm has hundreds of photos from this strange period over on Flickr organized into four main galleries: Linjeras och eldsvådor (accidents), Telefonstationer Stockholm, telephone stations in other parts of Sweden, and the Telefontornet.
