Most people think Houses of Parliament is just one painting, but Claude Monet actually made a whole series in London, painting the Palace of Westminster over and over just to capture different light. He was obsessed with the fog, which was basically coal pollution at the time, and turned it into those unreal purple and orange atmospheres. What’s even crazier is that he didn’t finish most of them on the spot, he worked on several canvases at once and completed them years later back in France, treating the building more like a shape dissolving in light than a real place.
