Tel Aviv-Yafo (Hebrew: תֵּל־אָבִיב-יָפוֹ; Arabic: تل أبيب, Tall ʼAbīb), usually called Tel Aviv, is the second largest city in Israel, with an estimated population of 391,300. The city is situated on the Israeli Mediterranean coast, with a land area of 51.8 square kilometres (20.0 sq mi). It is the largest and most populous city in the metropolitan area of Gush Dan, home to 3.15 million people as of 2008. The city is governed by the Tel Aviv-Yafo municipality, headed by Ron Huldai.
Tel Aviv was founded in 1909 on the outskirts of the ancient port city of Jaffa (Hebrew: יָפוֹ, Yafo; Arabic: يافا, Yaffa). The growth of Tel Aviv soon outpaced Jaffa, which was largely Arab at the time. Tel Aviv and Jaffa were merged into a single municipality in 1950, two years after the establishment of the State of Israel. Tel Aviv'sWhite City, designated a UNESCO World Heritage Site in 2003, comprises the world's largest concentration of Modernist-style buildings
