The first aquintance with ancient Safed, the city of Kabbalah

Today I start to tell about ancient and one of most mysterious Israel's cities. My tale is about Safed. Along with Jerusalem Safed "uncover itself" not at once and I still have more questions than have received the answers.
And now is my first short story. It is very important to know where Safed situated and what is its meaning for Jewish people.
So .... Safed (Tzfat) is situated in the mountains of Upper Galilee at about 900 meters above the sea levels and is Israel's highest city.
According to a legend Safed was founded by Noach's son Shem* after the Great Flood. It was one of five elevated spots fires were lit to announce the New Moon. Safed rose to fame by degrees and there were some different development ways in its history until 16th century, when its new era begins. The city became a center of Kabbalh when many Jewish religious scholars found their way to Safed after they were expelled from Spain in 1492 and among them were the famous kabbalists.
Due to its location Safed commands magnificent views to four cardinal directions and every time when I come to Safed I enjoy with unforgettable magnetic views.

* Shem means "name" or "renown", forefather of the middle peoples (Semetic).
