Research on urban space has a long tradition in classical studies. Current research of ancient urban spaces continues on in this tradition. It is essential to determine the position of research history in order to define the prospects of current urban studies in a more differentiated way: only those who are conversant with the history-of-science determination of their respective fields are able, intuitively and critically, to put innovative approaches and methods to the test. Based on the projects of the research group C-6, the various threads of history-of-science developments will be outlined and the current approaches defined in the context of constant re-orientation and new orientation of classical urban studies.
