Herzliya is a city in the central coast of Israel, at the Northern part of the Tel Aviv District. It has a population of more than 110,000 residents. Named after Theodor Herzl, the founder of modern Zionism, Herzliya covers an area of 11.6 square kilometres (8.3 sq mi). At its western municipal boundaries is Herzliya Pituah, one of Israel's most affluent neighborhoods and home to numerous Embassies, as well as prominent Israeli business people. The museum of Herzliya’s history, in one of the city’s original houses on Ha-Nadiv Street, documents the city’s growth. Near this museum is Herzliya Museum of Art, housed in the Yad le-Banim military memorial building on Wolfson St. West of the city is a Muslim holy site called Sidna Ali, which contains the tomb of Ali ibn Alil, a mosque and a number of buildings. To the northwest is the Tel Arsaf (Arsuf) archeological site, where the Apollonia National Park was established a few years ago. This site, which was inhabited from the Persian period (1500 years ago) until the Crusader period (1,000 years ago), has many impressive architectural remains of the Crusader town of Arsur, its fortress, surrounding wall and encompassing moat. Throughout the year, cultural events are held in the park, with music from around the world and festivals in the spirit of the Crusaders including period costumes.
