Haifa is the 3rd biggest city in Israel. If you are planning a tour in Israel, My recommendation is to include the sites, which the city of Haifa is offering (at least few of them).
1. Stella Maris- Stella Maris is a site which contain 3 interesting spots:
1.1 Stella Maris Observation- From that spot you can observe the Northern side of Haifa's Harbor. Nearby there is a cable car which leads you down the mountain, to Elijah's cave, and the Marine Museum.
1.2 Stella Maris Church - The Stella Maris Church is a beautiful structure, its interior walls covered with white marble panels so bright and well placed, that visitors sometimes think the walls have been painted.
The dome, decorated by the Maltese Carmelite Luigi Poggi (1924-1928), depicts episodes from the Bible, the most distinct being the scene of Prophet Elijah ascending to Heaven in a chariot of fire.
Underneath the altar, one can find Elijah’s cave where according to the Old Testament, the Prophet lived for some time. Inside the cave, there is an altar carved in the rock, with a small statue of the Prophet. Don't Miss it- It's a beautiful and Unique Church.

1.3. The Monument that was built by the French forces, to honor the Christians' victims which has been Massacred by the Muslim forces inside the church in the end of the 18th century.
2. Cave of Elijah- The Cave of Elijah refers to 1 Kings 19:8-9 in the bible, where it's written: ""So he got up and ate and drank. Strengthened by that food, he traveled forty days and forty nights until he reached Horeb, the mountain of God. 9 There he went into a cave and spent the night".
The Jews and the Christians (besides the Catholics) believe that this is the cave where Elijah hided from Ahab.
A Jewish pilgrim who visited cave during the period between 1270 and 1291 briefly mentions: “There is a cave, on the slopes of Mt. Carmel, and there the synagogue dedicated to Elijah, be he remembered for good. Above the cave, on the top of the mountain there is Elisha’s Cave". So it means that in the 13th Century, the Jews and some of the Christians believed that the cave in Stella Maris's Church, refers to Elisha.

5. German Colony- Haifa's German Colony, was Established in 1870 by the Templars. the Templars were Christian Germans who established several colonies in the country in the 19th Century. The first Wave of migration came to here in 1868, after they believed that the Messiah is about to com. Therefore, they decided to welcome him in the Promised Land. Because they believed that the Messiah is about to come, they even didn't built Churches, due to their believing that the 3rd Temple is going to be rebuilt few years from now.
