The Sudak and Novyi Svit mountains consist of robust organic limestone formed by colonies of corals, sponges, bryozoans, and lime-emitting algae that lived in a clear, warm sea at a depth of no more than 40-50 metres.

During the Late Jurassic era, around 130-150 million years ago, corals extracted calcium from seawater, died off, and a new generation developed on their remains.

This process led to the formation of rocky uplifts in shallow waters around the islands of present-day Sudak and Novyi Svit.

The Main Ridge, stretching from Cape Aya in the west to Chatyr-Dag and Qarabiy yayla in the east, contains the remains of a large barrier reef that once existed on the northern edge of the Tethys Ocean.

In porous reefs washed with water, the dissolved calcium carbonate from the skeletons of reef-builders is deposited in the voids, strengthening the coral-algae structure.

The fossils and calcite crystals can be polished to a lustrous shine, making them a beautiful decorative stone due to their intricate shapes.

[1] Located at the eastern foot of Mount Perchem, on the border of the Sudak State Enterprise vineyards, is a sulphur spring.

The water is sulphate-hydrocarbonate-sodium with a mineralisation range of 0.82 to 0.93 g/l and contains significant amounts of hydrogen sulphide, iodine, bromine, and other trace elements.

[10] Further research was conducted in 1993-1994, revealing that the monastery located under the southern slope of the Perchem and Lysaya peaks was relatively better preserved than other cloisters in the Sudak valley.

The complex covered an area of 215 square metres and comprised a temple, an inner household courtyard, and a dwelling - a cell that also served as a refectory.

A fragment of the inscription on the fresco has been preserved: "...the Temple of the Great Martyr and Infallible Panteleimon was built from the foundations by the work of..." An inscription was also found on the plaster: "Lord, help Zacharias, presbyter and ... sealed ..." The lack of conservation and protection of excavated foundations is a significant issue as they are deteriorating rapidly.

During the battle for the liberation of Sudak on 14 April 1944, the 979th Fighter Aviation Regiment pilots sank barges with retreating Germans and bombed an artillery battery on the slope of Mount Perchem.

[10] The Perchem massif includes a specially protected natural area in Russia known as the Park-Monument of Garden and Park Art.

[15] The conservation objectives are to preserve the plantation of valuable tree and shrub species listed in the Red Data Books of the Russian Federation and the Republic of Crimea.

[15] Although Koktebel was the primary destination for cultural figures in eastern Crimea during the early 20th century, Sudak also attracted creators.

Sudak is the subject of a well-known poem by Mikhail Viktorovich Pomrening (pseudonym Dionis), dated 1929, which is dedicated to the events of the civil war in Crimea but written in the aesthetics of the Silver Age.

Numerous unpublished works of the author have been preserved in the archive of poet Grigory Petnikov, which are now housed in the Literary and Art Museum of Old Crimea.
