The team of archaeologists led by Dr. Alexander Tamm (FAU, Friedrich-Alexander-Universität Erlangen-Nürnberg) and Prof. Dirk Wicke (Institute of Archaeological Sciences, Goethe University Frankfurt) has returned from its field research in northern Iraq without artifacts, but with many new insights. Over the past months, the ten-strong team has examined a building complex at the Gird-î Kazhaw site in the Kurdistan region of Iraq. The structure, which was first discovered in 2015, was probably built around 500 AD. Its purpose had, however, so far been unclear.
