Ethiopia has extensive historic sites, particularly in the north of the country, where the visitor can see constructions dating from the first millennium BC, the stelae and tombs of the Axumite kings, rock hewn churches dating from the 4th century, the monasteries of Lake Tana and the 13th century monolithic rock hewn churches of King Lalibella in Wollo. In the east, the 1000 year old city of Harer, with its 99 mosques, is the fourth holiest place in Islam, after Mecca, Median and Jerusalem. South of Addis Ababa there are a number of Neolithic sites, including the 1.5-1.8 million year old site at Melka Kunture (Oromia Region) and the 400 stelae at Dilla in Sidamo (Southern Region). Elsewhere in the southern region there are remote, medieval monasteries and in Jimma, in Oromia, there is the recently resorted palace of Abba Jiffar, the last independent king of the area.
Many archeologists and anthropologists proved that the human species originated in Ethiopia. In 1994 the oldest human remains ever discovered, the 4.4 million old bones of Homo Ramidus Afarensis, were found in Ethiopia's Afar Region - the previous record was held by "Lucy" or "Dinkinish" (Amharic for "wonderful"), who at 3.4 million years was a relative youngster.
