"Acre is a historic walled port-city with continuous settlement from the Phoenician period. The present city is characteristic of a fortified town dating from the Ottoman 18th and 19th centuries, with typical urban components such as the citadel, mosques, khans and baths. The remains of the Crusader town, dating from 1104 to 1291, lie almost intact, both above and below today's street level, providing an exceptional picture of the layout and structures of the capital of the medieval Crusader kingdom of Jerusalem." - in: http://whc.unesco.org/en/list/1042
"Masada is a rugged natural fortress, of majestic beauty, in the Judaean Desert overlooking the Dead Sea. It is a symbol of the ancient kingdom of Israel, its violent destruction and the last stand of Jewish patriots in the face of the Roman army, in 73 A.D. It was built as a palace complex, in the classic style of the early Roman Empire, by Herod the Great, King of Judaea, (reigned 37 – 4 B.C.). The camps, fortifications and attack ramp that encircle the monument constitute the most complete Roman siege works surviving to the present day." - in: http://whc.unesco.org/en/list/1040

"Petra is an archaeological site in southwestern Jordan, lying on the slope of Mount Hor in a basin among the mountains which form the eastern flank of Arabah (Wadi Araba), the large valley running from the Dead Sea to the Gulf of Aqaba. It is renowned for its rock-cut architecture.
The site remained unknown to the Western world until 1812, when it was discovered by Swiss explorer Johann Ludwig Burckhardt. It was famously described as "a rose-red city half as old as time" in a Newdigate prize-winning sonnet by John William Burgon. UNESCO has described it as "one of the most precious cultural properties of man's cultural heritage."In 1985, Petra was designated a World Heritage Site. It is one of the "New Seven Wonders of the World"." . in: wikipedia.
