Integrated geophysical surveys including magnetometer, gradiometer and seismic refraction were performed in the Suchon area, Kongju, Korea, which revealed three locations of buried architectural features. The magnetometer survey identified four main anomalies that were further tested using the gradiometer. Application of the second vertical derivative and the high‐pass filtering techniques to the magnetometer data isolated the deeper sources and enhanced the near‐surface features. Depth was estimated using magnetometer data and seismic refraction analysis. The study identified three promising areas that are strongly recommended for excavation, which can be seen in the northeastern and southwestern parts of the study area. They are strongly linked to shallow historical features, i.e. brick tomb structure, pottery collection and stone‐mound tomb, that were dominant during Baekche rule in Suchon area and therefore are believed to be from the Baekche period.
