This beautiful window is located at the end of Tram's 10 and 11, in Melkmarkt.
I love it and stopped to photograph it today. Later, editing it, I was bemused by the way there were almost no straight lines, beyond the window frames, on the ancient building that houses it.
The warmth of the window, the way the instruments are displayed, the light ... it all called to me so much more than the building itself and so I cropped the image down to the window.
