From http://www.newadvent.org/cathen/08344a.htm : Jerusalem is situated in latitude 31° 46' 45" N. and longitude 35° 13' 25" E. of Greenwich, about 32 English miles in a straight line from the Mediterranean on the west, and 13 from the Dead Sea on the east. It stands on the crest of a chain of mountains which traverses the Land of Israel from north to south, and the highest point of which, at the northwest corner of the city, is 2577 feet above the level of the Mediterranean, and 3865 above that of the Dead Sea. Owing to this difference of level the western slope of these mountains, towards the Plain of Sephela, which extends to the Mediterranean, is gentle, while that to the east is very steep. A girdle of high hills surrounds the city, forming a sort of natural rampart. On the north is Mt. Scopus (2705 feet), next to it, on the east, the Mount of Olives (2665 feet), beyond which again is the Mount of Offence (2410 feet) (1 Kings 11:7; 2 Kings 23:13). To the south is the Mount of EvilCounsel (2549 feet), which forms the eastern boundary of the Plain of Raphaim, and next, on the southwest, comes a hill (2557 feet) to which no name has been given. Towards the northwest the city is more exposed; at some distance in that direction it is dominated by the Nebi Samwil, the ancient Maspha, which has an altitude of 2935 feet. Notwithstanding the difficulty of access in its natural situation, Jerusalem is the centre of a network of ancient roads which connect it, on the east, with Jericho and the Jordan; on the south, with Hebron and Gaza; on the west, with Jaffa and Caesarea; on the north, with Samaria and Galilee. It was, however, situated beyond the great military and commercial highways between Egypt and Assyria.
