Mount Sinai. Mount Sinai, also known as Mount Moses, is a mountain in the Sinai Peninsula of Egypt that is a possible location of the biblical Mount Sinai, which is considered a holy site by the Abrahamic religions. Mount Sinai is mentioned many times in the Book of Exodus and other books of the Bible, and the Quran. According to Jewish, Christian, and Islamic tradition, the biblical Mount Sinai was the place where Moses received the Ten Commandments. Mount Sinai is a 2,285-metre moderately high mountain near the city of Saint Catherine in the Sinai region. It is next to Mount Catherine. It is surrounded on all sides by higher peaks of the mountain range. Mount Sinai's rocks were formed in the late stage of the Arabian-Nubian Shield's evolution. Mount Sinai displays a ring complex that consists of alkaline granites intruded into diverse rock types, including volcanics. The granites range in composition from syenogranite to alkali feldspar granite. The volcanic rocks are alkaline to peralkaline and they are represented by subaerial flows and eruptions and subvolcanic porphyry. Generally, the nature of the exposed rocks in Mount Sinai indicates that they originated from differing depths. Biblical Mount Sinai Immediately north of the mountain is the 6th century Saint Catherine's Monastery. The summit has a mosque that is still used by Muslims, and a Greek Orthodox chapel, constructed in 1934 on the ruins of a 16th-century church, that is not open to the public. The chapel encloses the rock which is considered to be the source for the biblical Tablets of Stone. At the summit also is Moses' cave, where Moses was said to have waited to receive the Ten Commandments. There are two principal routes to the summit. The longer and shallower route, Siket El Bashait, takes about 2.5 hours on foot, though camels can be used. The steeper, more direct route is up the 3,750 steps of penitence in the ravine behind the monastery.
