Which London building did Claude Monet paint in a series during the early 1900s?

Claude Monet painted the Houses of Parliament in a series during the early 1900s.

Monet began the series during visits to London between 1899 and 1901, then continued working on the canvases after returning to France. He painted the Gothic riverside building from different viewpoints and under changing conditions of fog, light, and atmosphere. The structure often appears partially dissolved by mist rather than sharply outlined.

The series belongs to Monet’s broader interest in painting the same motif repeatedly. Like his Rouen Cathedral and haystack paintings, the London works examine how color and form change with weather, time of day, and illumination.

The building is officially the Palace of Westminster, but Monet’s series is conventionally known as Houses of Parliament. It should not be confused with his London paintings of Waterloo Bridge and Charing Cross, which were made during the same general period.
