The Baha'i Gardens in Haifa and Acre are among the most popular sites in Israel. Their unique design, combining geometrical shapes and exquisite detailing with loving conservation of natural and historic landscape features, leaves an indelible impression on visitors. In July 2008, the Baha'i Gardens in Haifa and Acre were inscribed on UNESCO's World Heritage List, in recognition of their "outstanding universal value" as holy places and places of pilgrimage for the followers of the Baha'i Faith.
