Newmarket-on-Fergus Marconi', Degna Marconi, the daughter of the inventor of the radio, Guglielmo Marconi, describes in detail holidaying on the Dromoland Estate in 1905. In late June 2004, the first summit to take place between the US and the enlarged EU 25 Member States took place in Newmarket at Dromoland Castle. In the Spring of 2007, six skeletal remains were found during the archaeological monitoring of improvement works to a local water network near Barnhill, Newmarket-on-Fergus. Dating showed that the remains were Pre-Christian. The town is situated about 10 km from Ennis. As its name implies, it lies on the River
Invention of radio science historians have taken the position that this was the first transatlantic radio transmission. Critics have claimed that it is more likely that Marconi received stray atmospheric noise from atmospheric electricity in this experiment. The transmitting station in Poldhu, Cornwall used a spark-gap transmitter that could produce a signal in the medium frequency range and with high power levels. Marconi transmitted from England to Canada and the United States. In this period, a particular electromagnetic receiver, called the "Marconi magnetic detector" or "hysteresis magnetic detector", was developed further by Marconi and was successfully used in his early transatlantic work (1902)
