Abstract : The Early Medieval valley settlement of Thunau am Kamp in Lower Austria has been under archaeological excavation for 10 years.The site was occupied during the 9th and 10th centuries AD according to potsherds, which seem to indicate two phases of activity: in the older phase ovens were placed in the corners of houses while during the younger phase they are found in the middle of the wall.On the earth's surface, when you hold a compass and the needle points to north, it is actually pointing to magnetic north, not geographic (true) north.
These paleomagnetic signatures are fixed when ferromagnetic materials such as magnetite cool below the Curie point, freezing the magnetic moment of the material in the direction of the local magnetic field at that time.
The direction and magnitude of the magnetic field of the Earth at a particular location varies with time, and can be used to constrain the age of materials.

Linford, English Heritage) The material appears to be well heated as it is reddened.
The Earth's magnetic core is generally inclined at an 11 degree angle from the Earth's axis of rotation.
