The Gog Magog Downs (also known as the Gog Magog Hills or simply the Gogs) are a range of low chalk hills, extending for several miles to the southeast of Cambridge in England. The highest points are marked on Ordnance Survey 1:25000 maps as "Telegraph Clump" at 75 m (246 ft), Little Trees Hill and Wandlebury Hill, both at 74 m (243 ft). The area is undefined but is roughly the elevated area lying north west of the 41 m (135 ft) col at Worsted Lodge.
Unlike the nearby hills of the Newmarket Ridge, which have steep sides but very flat tops, these hills have large drops between summits and as such have quite a distinctive appearance; Little Trees Hill looks particularly good from Huckeridge Hill near Sawston. The hills therefore have relatively high topographic prominence. Other tops include: Limepit Hill 56 m (184 ft)— Mag's Hill— Copley Hill— Meggs Hill— Fox Hill— Clarke's Hill— White Hill
In English folklore and the Matter of Britain Gogmagog was a giant, and according to Geoffrey of Monmouth's influential 12th-century Historia Regum Britanniae one of the inhabitants of Albion discovered by Brutus of Troy and his men. He was the last of the giants that they killed, and was thrown from a cliff by Corineus.
Gog and Magog (/ɡɒɡ/; /ˈmeɪɡɒɡ/; Hebrew: גּוֹג וּמָגוֹג Gog u-Magog) are names that appear in the Hebrew Bible (Old Testament), notably Ezekiel, and the Book of Revelation, sometimes indicating individuals and sometimes lands and peoples. Sometimes, but not always, they are connected with the end times, and the passages from the Book of Ezekiel and Revelation in particular have attracted attention for this reason. From ancient times to the late Middle Ages, Gog and Magog were identified with Eurasian nomads such as the Khazars, Huns and Mongols and were conflated with various other legends concerning Alexander the Great, the Amazons, Red Jews, and the Ten Lost Tribes of Israel, and became the subject of much fanciful literature. They appear in the Qur'an as Yajuj and Majuj (Arabic: يَأْجُوج وَمَأْجُوج Yaʾjūj wa-Maʾjūj), and the Muslim world identified them first with Turkic tribes from Central Asia and later with the Mongols. In modern times they remain associated with apocalyptic thinking, especially in the United States and the Muslim world.
