Summary:
A restoration should be required to prevent demolition of extant other parts and walls of a church. Because any excavation cannot generally be made in historical buildings, restoration of such buildings has been decided without regarding the foundations of these structures. In these cases, some problems such as collapse and demolishing of structure may be occurred in historical buildings. Before the restoration of such historical buildings, position of foundation in the buildings must be determined by using ground penetrating radar (GPR) which is a non-invasive technique can give results with high resolution for dealing with these problems. The study was aim to determine foundation’s depths/size/shape/lateral extents of walls of the Hagios Thedoros Church by using GPR. Amplitude-slide maps with the method were created on the investigation area located at north of the Hagios Thedoros Church to be the oldest church in the Old Gumushane on NE of Turkey. These maps for different depths were interpreted. Strong reflections resulted from foundation structures remains and collapsed stones of the church were shown as dashed red lines and arrows on these maps.
