when was mount rushmore built

Mount Rushmore was built between 1927 and 1941 , taking about 14 years from the start of construction to completion. The carving work itself lasted roughly 6.5 years , with about 400 workers using dynamite, drills, and chisels to shape the four presidential faces into the granite of the Black Hills in South Dakota.

When construction started

• Actual carving began in October 1927 , after sculptor Gutzon Borglum secured funding and finalized the site.

• The idea and early planning date back to the early 1920s, when South Dakota historian Doane Robinson first pitched the monument to boost tourism.

When it was finished

• Work officially ended in October 1941 , months after Borglum’s death in March of that year; his son, Lincoln Borglum, supervised the final stages.

• The project cost just under $1 million , funded mostly by the federal government with some private donations.
