Prompt

Build a model of Cologne Cathedral. The model recreates the Gothic cathedral at true architectural scale: two openwork carved spires at the front facade, dark pitched roofs covering the nave and transept, and a polygonal apse on the east end. The facades are filled with pointed-arch lancet windows and circular rose windows, the exterior walls are supported by rows of flying buttresses, and the entrances feature deeply recessed pointed-arch portals. The whole structure sits on a light-colored rectangular base, with the building composed of pale limestone walls, dark gray roofs, and a few warm-toned accent elements.
