Geography
Located at the crossroads of Africa, Asia and Europe, Egypt is built around the Nile Valley, a very fertile land bordering the river and bounded by 2 seas : the Mediterranean Sea (to the north) and the Red Sea (to the east). The thin area on either side of the Nile was historically where 90% of the population settled. To the east of the valley is the Arabian Desert, bounded by a high ridge of mountains. To the west is the Libyan Desert which stretches across the top of North Africa.
The demarcation line in Cairo, the capital city, separates Lower Egypt (everything north of Cairo) from Upper Egypt (everything to the south). To the east, across the Suez Canal is the triangular wedge of Sinai with Mt Sinai and Mt Catherine, the highest mountain in Egypt (2642m).
