The Garabit Viaduc
Nicknamed "the Eiffel Tower of Cantal", the Garabit Viaduct still attracts admiration, 130 years after its construction by... Gustave Eiffel!
This iron span is 565 m long, culminates at 122 m above the river, and was the “highest viaduct in the world”; until 1886. Its arch was also the longest span in the world.
