Abstract

Ground penetrating radar (GPR) surveys were conducted at the former Krošinskių Manor, located in Rokiškis, Lithuania, searching for remnants of the manor complex. The manor belonged to the Krošinskių family, who ruled the Rokiskis area for 200 years, dating back to the 16th century. Due to modern development and a lack of restoration resources, many of the manor’s past structures are no longer standing, and their locations are left unknown. Earlier structures include defensive fortifications, servant quarters, a sauna, and a mill. In the search for the missing buildings, two GPR grids were collected at the site using a Sensors and Software PulseEkko GPR system with a 500 MHz antenna, with 0.25 meter line spacing. Both GPR grids were processed using GFP_Edit, EKKO_Project, and GPR Slice. The first GPR grid measured 9.5 meter x 32 meter, resulting in 38 lines, and the second grid measured 27 meters in width, resulting in 108 lines taken at various lengths. Within the first GPR grid, 9 meter-wide anomalies in the form of horizontal bars were found at depths ranging from 0.5 to 0.7 meters. These likely represent walls from the past structure. Within the second GPR grid, a 13.5 meter rectangular anomaly can be seen at a depth of 0.7 meters. This anomaly is likely the remnants of the manor’s defensive fortifications. The results of the GPR survey will provide local Lithuanian archaeologists with important data that will aid in future excavations, as well as provide the citizens of Rokiškis with a better understanding of a prominent historical site in their community.
