The ‘Panorama’ is the oldest part of the building, showing the road construction in the early 20^th century with the use of the method worked out by engineer John Loudon McAdam who has revolutionized road construction by offering a new roadbuilding technique (macadam). Visitors can learn about the work of a road worker, bridge carpenter, paver and a gate-keeper, see handheld equipment and historical tools. Nearby are old bitumen containers of 1960s, made of concrete and equipped with a heating system connected to a boiler. They made it possible to produce 12, 25 and 30 tons bituminous mass per day depending on the equipment that changed over the years with the industrial progress.
