Archaeological excavations on the Castle Hill in Pułtusk lasted ten years, without winter breaks. They covered a significant part of the castle courtyard, which generally corresponded to the area of the center of the older stronghold. The historical phases were formed by layers of wooden structures with a unique state of preservation, as were the accompanying layers, filled with a wealth of organic remains and a variety of artefacts. The bishop's stronghold was built on the ruins of an older defensive structure in the first half of the 13th century. An important feature of the later stratification process was the dynamic growth of layers and accompanying structures. The discovered wooden constructions formed a network of streets, filled with dense development of several settlement phases. The research was interrupted by the political and economic events of the mid-1980s. The secured entire material found its place in the exhibition halls and warehouses of the local museum.
