The Glenfinnan Viaduct is an impressive feat of engineering. Built at the dawn of the 20th Century, there are 21 arches spanning 416 yards – most astounding for the time, it’s made entirely of concrete, without being reinforced. The Glenfinnan Viaduct has featured in many movies, including the Harry Potter series.
