Abstract
The researchers and students of the Department of Geophysics and Space Sciences, Eötvös Lóránd University have been carrying out geophysical surveying in the Roman age town Porolissum. Porolissum is located 20 km east to Zalau, Romania. Magnetic surveying is one of the most frequently used geophysical methods in archaeological prospecting. We used GSM-19 Overhauser magnetometers. When the soil is disturbed its susceptibility also changes. That is why we can see these structures in the magnetic anomaly map. We were able to map the structure of the fort in Porolissum with magnetic surveying. The results and their interpretation are in agreement with the results of the former archaeological explorations.
