Mount Manjil rises above the Sudak valley from the east, the highest point of the Tokluk ridge (500 m above sea level). The mountain owes its second name - Ai-George - to a medieval Greek monastery in the name of St. Great Martyr George, which was located at its foot in the Middle Ages.

According to Archbishop Gabriel, the place was empty when the Greeks left from here at the end of the 18th century, and the vault and walls collapsed, so that only ruins remained. Later, during excavations, a stone slab of the 3rd century BC was found in the masonry of its walls. n. e., with a dedication to the Greek goddess Demeter, who was honored in the Bosporus. It can be assumed that the Christian monastery appeared on the site of an older pagan temple. If this assumption is correct, then the age of the religious building at the foot of Ai-George may exceed two thousand years.

Ai-George is well visible from anywhere in the city. A treeless steep peak crowned with a triangulation sign almost imperceptible from below, to the left of it there are cliffs of thousand-year-old rocks and dense impenetrable forests, to the right, on the southern spurs, there are almost lifeless loose gullies and ravines.
