Cathedrale de Rouen

This painting is part of a series of paintings to highlight the effects of light on a particular subject. It is Monet’s most exhaustive series of paintings about a single subject.
The series of paintings were viewed and praised by fellow painters Camille Pissarro and Paul Cézanne while it was on exhibit.
Monet encountered difficulty painting the subject due to the complexity of the motif and the light. These complications eventually gave him nightmares.
