The Rose windows in this church are huge and very detailed. This is the south window.
Wikipedia: The window that is central to the well-known Gothic façade of Notre Dame, Paris, is of more distinctly Gothic appearance, with mullions in two bands radiating from a central rondel, each terminating in pointed arches. It was this window, completed about 1225, that set the pattern for many other rose window including those of the transepts at St Denis and the gigantic and complex window in the south transept at Notre Dame.
