The Holy Land draws mainly religious tourism, however, it also has important archaeological and ecological sites. It is the country with the largest number of museums per capita in the world. The places that are of the greatest interest are the area of the Temple, the Wailing Wall, The church of the Holy Sepulchre, Skull Hill (Golgotha) and the Dome of the Rock in Jerusalem, Tel Aviv, which is the cultural and financial centre, the Sea of Galilee in Tiberias, the Red Sea, Nazareth, Haifa and the Roman ruins of Caesarea. Another highlight is the Dead Sea, where excess salt in the water causes the body to float.
