From 1890
he concentrated on series of pictures in which he painted the
same subject at different times of the day in different lights---Haystacks
or Grainstacks (1890-91) and Rouen Cathedral (1891-95) are the
best known.
He continued
to travel widely, visiting London and Venice several times (and
also Norway as a guest of Queen Christiana), but increasingly
his attention was focused on the celebrated water-garden he
created at Giverny, which served as the theme for the series
of paintings on Water-lilies that began in 1899 and grew to
dominate his work completely (in 1914 he had a special studio
built in the grounds of his house so he could work on the huge
canvases). In his final years he was troubled by failing eyesight,
but he painted until the end. He was enormously prolific and
many major galleries have examples of his work.
