Safed is a city in the Northern District of Israel. Located at an elevation of 900 metres (2,953 ft), Safed is the highest city in the Galilee and in Israel. Due to its high elevation, Safed experiences warm summers and cold, often snowy, winters. Since the 16th century, Safed has been considered one of Judaism's Four Holy Cities, along with Jerusalem, Hebron and Tiberias; since that time, the city has remained a center of Kabbalah and Jewish mysticism. Interest in the Kabbalah was brought to the city by the rabbi Isaac Luria in the 16th century.
Due to its mild climate and scenic views, Safed is a popular holiday resort frequented by Israelis and foreign visitors. In 2015 it had a population of 33,358.
