This probably continues westwards beyond the limits of the trench and its extent and function could not be ascertained within the current investigation. Directly below the floor layer level a layer consisting of larger and smaller stones (1071) was investigated. This is interpreted to represent the foundation and ground levelling in the first phase of the construction (see Appendix 3h). It is possible that the stone accumulation 1060 should also be seen as part of this layer, but with an unclear stratigraphic position.
