An elaborate mid-19th-century presentation sheet illustrating French engineer Thomé de Gamond’s pioneering proposals for a submarine Channel tunnel beneath the Dover Strait. The map combines geological sections, seabed profiles, engineering diagrams, and panoramic views, including detailed plans and cross-sections of the proposed “Étoile de Varne,” a mid-Channel ventilation and railway station to be built on the Varne sandbank, together with a series of thirteen artificial îlots along the route, presumably constructed from excavations. It also includes a geological diagram of the submerged chalk ridge between Dover and Calais, a study map of the proposed alignments with branches to Dover, Calais and Boulogne, and a panoramic perspective taken from Marquise. Aimé Thomé de Gamond (1807–1876), the French engineer and geologist widely regarded as the father of the Channel Tunnel, spent over thirty years developing the first properly grounded proposals for a fixed link between Britain and France. His detailed geological surveys, underwater inspections, and numerous official submissions to both governments formed the earliest comprehensive technical foundation for the project eventually realised in 1994. This sheet is a fine and decorative example of his engineering advocacy, produced in 1855 at the height of his campaign to demonstrate the feasibility of the tunnel.
