Landscape painting continued to be popular in late-19th- and early-20th-centuries. Many artists left the bustle of the city and headed for rural landscapes infused with light where they would have an opportunity to a paint en plein air and observe nature first hand. As a result some of the most innovative experiments in colour, viewpoint, the application of paint and interpretation took place outside of the cities.
Revolutionary artists such as Gustave Courbet, who pushed the boundaries of landscape painting by making it both tactile and visual, paved the way for the next generation of painters to break from the Royal Academy of Arts — the Impressionists including Claude Monet, Camille Pissarro, Auguste Renoir, and Alfred Sisley.
The 19th Century also saw the birth of landscape photography … many artists felt it was no longer necessary to create strictly representational paintings and preferred to express personal spiritual and emotional relationships with the landscape.
The Post-Impressionists, including artists as diverse as Paul Cézanne, Vincent van Gogh, Georges Seurat, and Paul Signac, did not exhibit together and were never a unified group, but they shared a commitment to exploring the mechanisms of artmaking.
Some artists including Monet and Cézanne returned again and again to the same scenes to capture the changing light and the passing seasons.
In the second half of the 20th century, the definition of landscape was challenged and evolved to include like urban landscapes, cultural landscapes, industrial landscapes, and landscape architecture.

Today, the landscape continues to be a subject artists turn to when contemplating the ways we relate to the places where we live and the impact we as humans have on the land.
