Tel Aviv is Israel's second largest city. With a population of about 390,000, mainly Jews, Arabs make up about 4 [%] of the population. Tel Aviv is bordered by the eastern Mediterranean Sea and has an area of 52 square kilometers. Tel Aviv City was originally founded in 1909 by a group of Jewish immigrants to escape the nearby ancient port city of Jaffa (Hebrew: יפו, Yafo; Arabic: يافا, Yafa) was built gradually with expensive house prices, but Tel Aviv grew more than the predominantly Arab Jaffa. In 1950, two years after the founding of Israel, Tel Aviv and Jaffa merged to form Tel Aviv-Jaffa City. Today Tel Aviv is Israel's political center and is considered the most international economic center and cultural capital of Israel. Tel Aviv is booming, with high-rise buildings and a famous diamond trading center; Rabin Square is in front of the municipal building. Rabin Square has marks to commemorate Rabin's assassination and a graveyard; and triangular memorial sculptures to mourn the slaughtered Jewish compatriots.
