The tomb is located adjacent to the 17th-century Villa Griffone/Villa Marconi, located on via Celestini #1 in Pontecchio Marconi, about 15 kilometers outside the city of Bologna in Emilia Romagna, Italy. The Museo Marconi celebrates the discoveries and advances of the Marconi in the areas of electricity and radio communication, as well as a general history of the development of radiocommunication. It houses some of the scientific instruments and products used and developed by
Guglielmo Marconi day during which the entire transatlantic path was in daylight. It is now known (although Marconi did not know then) that this was the worst possible choice. At this medium wavelength, long-distance transmission in the daytime is not possible because of heavy absorption of the skywave in the ionosphere. It was not a blind test; Marconi knew in advance to listen for a repetitive signal of three clicks, signifying the Morse code letter "S". The clicks were reported to have been heard faintly and sporadically. There was no independent confirmation of the reported reception, and the transmissions were difficult to
