Nehaj fortress is an interesting example. It was sort of obsolete from the start, but not useless. At the time of its planning and construction, fortresses were already in general adapted to the role of artillery in sieges. Some Dalmatian towns were constructing modern renaissance or star forts at the time. However, due to local limitations, a lack of space on that hill overlooking Senj, it was impossible to build a proper star fort there. Therefore, even though there are visible Renaissance influences in Nehaj, it was built tall and narrow, more like a medieval fort.
