Major explorations after the Age of Discovery to locate the source of the River Nile. Expeditions by Burton and Speke (1857–1858) and Speke and Grant (1863) located Lake Tanganyika and Lake Victoria. It was eventually proved to be the latter from which the Nile flowed. Explorers were also active in other parts of the continent. Southern Morocco, the Sahara and the Sudan were traversed in many directions between 1860 and 1875 by Georg Schweinfurth and Gustav Nachtigal. These travellers not only added considerably to geographical knowledge, but obtained invaluable information concerning the people, languages and natural history of the countries in which they sojourned. Among the discoveries
Dillington House Court was William Speke of Jordans near Ilminster, father of the celebrated discoverer of the River Nile John Hanning Speke. It is now a Grade II* listed building. Dillington House was the country residence of George III's Prime Minister, Lord North who acquired it through marriage to Anne Speke. The stables which were built in the 18th or early 19th century were remodelled in 1875 by George Nattress and later in the 1960s when the Coach House was converted into a theatre. The two lodges adjacent to the main gate are also Grade II* listed and are in private ownership.
