Which French cathedral did Claude Monet paint in a famous series?

Claude Monet painted Rouen Cathedral in a famous series.

Monet created his Rouen Cathedral paintings in the 1890s, studying the cathedral façade from changing positions and under different lighting conditions. The series focuses less on architectural documentation than on the shifting appearance of stone.

He often worked from rooms near the cathedral and continued refining the canvases in his studio. Different works show the façade in varied weather, seasons, and times of day, demonstrating how atmosphere could transform a familiar subject.

The series contains more than 30 paintings, with 30 commonly cited as the core group. Monet did not intend the paintings to function as identical replicas. Instead, their differences make the central idea visible: color and surface appearance change constantly with light.
