Haifa is the main city of northern Israel and the third-largest city in the country, with a population of about 267,800. Situated in a broad natural bay between the beautiful Mediterranean Sea and the Carmel Mountain, the city's terraced landscape offers a rich variety of breathtaking panoramas. The industrial region of Haifa is north of the city, near the Wadi Kishon. Haifa is home to one of the two oil refineries in Israel. Matam (Mirkaz Ta'asiya v'Meida/Scientific Industries Center), the largest and oldest business park in Israel, is located at the southern entrance to the city, hosting manufacturing and R&D facilities for a large number of Israeli and international hi-tech companies such as such as Intel, Elbit, Zoran, Microsoft, Philips and Amdocs. The port of Haifa also has the heaviest traffic from passengers and cargo as it is Israel`s busiest port.
