Semizovac was once a county or the administrative center of the region, a crossroads of road and rail roads to Sarajevo, Zenica and Tuzla. It is well known to all fans of fishing, who visited the clear green waters of the rivers Bosnia and Ljubinje. This place once had a sawmill and was a place of separation of manganese ore from nearby mines in Čevljanovići. Manganese and timber from sawmill called Srednje was exported by rail to all parts of the world. The stagnation of the place began by shutting down the mine, which is visible even today. Many people still remember that Semizovac was once the only place with services for chain saws, which have been deposited for reparation from all over the former Yugoslavia and beyond.
Today there is no tangible development in Semizovac. You will not meet a single tourist who visits this place, but there is one interesting thing that Semizovac stands out from the rest of the world. Specifically, it is about the fact that believe it or not, Semizovac got electricity immediately after New York. In New York, the first light bulb lit up in 1881, while according to the written findings and some chroniclers, the first light bulb lit up in Semizovac in 1890, which was also the first light bulb in Bosnia and Herzegovina. And Sarajevo is not comparable to Semizovac, because the electricity was introduced in Sarajevo in 1895. The light bulb which was used in Semizovac was with a simple construction, conventional bulb of 1.5 V. It was an artificial light source created by passing electricity through a thin filament of tungsten, warming it to heat, which is then produced light. Today’s light bulbs are more or less based on the same principle of operation, with a number of variations so we have incandescent bulbs, halogen bulbs, neon bulbs..etc.
Bearing all this in mind, the Government of Semizovac made a monument in honor of the first lighted lamp in Bosnia and Herzegovina in the center of Semizovac, and one of the first to ever illuminate the entire world. This monument is interesting and nice, as well. We can only hope that this simple object such as a light bulb, which we all use everyday and everywhere, will last in our lives for a long time finding its usage.
