 Zobaczmy, że studied study cover an area of a section of the valley of two smaller rivers, Milakówka and Volska, situated at the height of village named Strozena in North Eastern Poland. The set area of about 700 hectars has been covered with a forest since at least the late 19th century and therefore long time. Identification of archeological heritage within its borders was hindered. W latach 2012 do 2016 gręta na programie narzędzińskiego rozwoju humanitarnych, nazywany Katalog Warmia i Mazurya Strongholds, został przypośredniony w reakcji profesora Zbigniew Kobyliński. Jako części gręta, nieodawna perspektywana rozwoju dyskusji, został przypośredniony używający data ALS. To pozwalało nam sprawdzić formę range of fortification of own physical form of the formerly known strongholds Struzina 21, situated on the edge of the mentioned valley and also to identify a formerly unknown defensive settlement Struzina 24, located only one kilometer in a straight line from the former. Moreover, we have recorded a number of anthropomorphic features that could not be completely verified on site at the time. The project titled not invasive identification of archeological heritage in the area of Struzina village was executed in the spring of 2018. The main objective of the project was to verify barrels occurring in the area, yet information on the other futures was also successfully obtained, which allowed the researchers to recreate main points of history of this micro region manifested in its landscape. The project was implemented with the contribution of archive research in which archival maps, source text and data of archeological sites collected under the project Polish archeological record were used. These data were collected and mapped in GIS database and then compared with ALS data obtained under the project titled ISOC. In the course of ALS data processing, a number of anomalies from potentially as a result of human activity were determined. These points were verified on site during survey prospections and documented. Moreover, for a single feature, also known invasive methods were performed using Barkington magnetic gradient. The result of the study is a map with marked archeological sites that can be classified according to their function and chronology. The first group was strongholds. This category involves two sites. Struzina 24 is a defensive settlement of about 0.4 hectares covering and exposed promotory surrounded from the three sites by a deep valley of a small stream cut off from the upland by three lights of dykes and molds. During the excavations in 2015 a historical material was obtained based on which it was concluded that the settlement had been inhabited at the turn of Latin A period by people classified as the west bar bar culture. At present the dykes and the molds are very difficult to identify, which is only partially due to erosion. They were most likely partially used for agricultural purpose as evidence by small faros orientat in the east-west direction, which are marks left after the field was plowed. Radiocarbon dating of carbon obtained from subsoils gave a time range of 1328 to 1445 AD. The next stronghold is Struzina 21. It's a two-face stronghold with a complex stratigraphy with an adjacent settlement outside the walls covering a total area of about 1.6 hectares. Like Struzina 24 it covers an exposed promotory and it cut off from the upland by a dyke and a mold. The older face should be linked to the people of the west bar culture and dated to Latin sea. Thermal mistens dating identified the period as 310 to 30 BC. This area was again used in the early Middle Ages, when in the place of the older settlements the stronghold was erected with fortification clearly manifested in the landscape. The chronological horizon was identified using radiocarbon dating to 777 to 991 AD. This stronghold would be then inhabited by the Baltic Prussian. The next group is Baros. In May 2018, as many as 16 potential archaeological sites were determined, in the surveyed area we recorded 9 Baros in total, which are interpreted as Baros dated to early Iron Age and linked to the people of west Baros culture. The largest ones are up to 1 meter tall, with 10 meter up to the 15 meter long. About 470 meters north of the defensive settlements, Tujna 24. Two Baros were examined, in which historical material was found, dated probably to Halsstad de and linked to the culture of west baro culture, which was profoundly influenced by the Pomeranian culture. This had the form of stoned earth mounds with a stoned chest embedded and into undisturbed soil below and surrounded with a circle of stones that enclose the chamber and outline the edge of the mounds. In the very same way, one can interpret result of noninvasive investigation using gradientometer. Measurements were taken in parallel manner in a 10 meter by a 10 meter excavation grid. On the magnetic map, a structure with a circle-like layout can be observed with numerous anomalies in the center. Two large assemblies in the center are most likely a relict of modern treasure hunter's excavation. The next one, it's perhaps filled with remains. Trace of former land cultivation were already mentioned in the description of the defensive settlements Tujna 24. Were characteristics of the object form as a result of plowing were and counted estimate at about 14 to 15 century. In the surveyed area more fields of this sort were distinguished, oftentimes better preserved. In such cases, ridges form as a result of plowing are wider and taller, which can translate into a longer period during which this type of field was used. The greatest recorded width of a ridge is 7 meters. The next group was former farm dwellings. Despite Tujna and its harment, Stabuniki never developed enough to gain the next administrative level. Changes in their internal planning can be spotted in the present day landscape. This is likely due to the fact that since about mid 16th century Struzina village was fifth owned by the Don family. It was under initiative the Manor buildings were erected in Struzina and Stabuniki. Evidence in source back in 1850. So maybe time for conclusions. The analysis of landscape element conducted based on historical sources and DTM data with the support of archaeological research findings allowed the history of the discussed micro region to be reconstructed. This is significant because each of these of the discussed site is located in a forest area. In this case the forest served as safeguard protection the historical landscape which allowed to be present until modern day. In area adjacent to Struzina where forest are gradually cut down due to agricultural reasons and because of the development infrastructure conducting such reconstruction work it's not possible particularly given the highly perishable element such as all traces of soil cultivation. Thank you.
