Mont Blanc: Lines Written in the Vale of Chamouni is an ode by the Romantic poet Percy Bysshe Shelley. The poem was composed between 22 July and 29 August 1816 during Shelley's journey to the Chamonix Valley, and intended to reflect the scenery through which he travelled. Mont Blanc was first published in 1817 in Percy Shelley and Mary Shelley's History of a Six Weeks' Tour through a Part of France, Switzerland, Germany and Holland, which some scholars believe to use Mont Blanc as its culmination.
