First settled around 3000 B.C.E. at the northern point of Haifa Bay, Acre is one of the oldest continuously inhabited settlements in the area, with a wealth of historic sites from almost every era of occupation. During Ottoman rule in the late 19th century, holy Bahá’í sites were constructed to honor the prophet who founded the religion, Bahá’u’lláh. These Bahá’í Gardens in Haifa and Acre are among the most visited and photographed places in Israel. In 2008, they were added to the list of UNESCO World Heritage Sites.
