This impressive structure, an integral part of the Montenvers Railway, offers visitors unparalleled views of the majestic mountains and the renowned Mer de Glace, France's largest glacier. Constructed in the early 20th century, the Viaduc de Montenvers stands as a testament to human engineering amidst the raw beauty of the Alps.
