Otkos (the Volga and Oka slopes) — a scenic, tree- and grass-covered high escarpment encircling the Upper Town of Nizhny Novgorod above the Volga and the Oka: a steep landslide scarp of the Volga Upland rising 80–100 metres above the rivers, along which run the Verkhne-Volzhskaya Embankment, Alexandrovsky Garden, and the Chkalov Staircase [1][2].

The nature of the phenomenon

The Oka–Volga watershed slope of the Volga Upland borders the upper town of Nizhny Novgorod in a narrow band from the southwest, west, north, and east. The complex landslide slopes of the Oka–Volga hillside are concave in form; steepness varies along the profile: greatest in the upper part of the slope, from 25° to 48°, and considerably less at the bottom owing to landslide deposits accumulated at the foot. Numerous terraces of denudational, erosional, and landslide origin run along the length of the slope [1][19].

Nizhny Novgorod geomorphologists regard the Otkos as an element of the Main Volga geoflexure of the Russian Plain. It sharply separates the elevated erosional right bank from the low-lying terraced left bank: the landslide landscapes of the Otkos resemble neither the plakor uplands of the upper town nor the trans-Volga plains [3][4].

Nizhny Novgorod residents divide the escarpment by river. The Volga escarpment stretches from the Kremlin along the Verkhne-Volzhskaya Embankment to Sennaya Square and on to Pechyory; its western section opens from Fedorovsky Embankment above Rozhdestvenskaya Street, and above the Oka the slope continues as the Oka escarpment. The escarpment along the Oka's course bears the additional name Dyatlov Hills; this name also refers to the ridge of hills from the mouth of the Oka to Kstovo — the northwestern extremity of the Volga Upland, rising 80–100 metres above the Oka and the Volga [1][4][19].

The Volga escarpment is a favourite recreational spot for the city's residents; in a public vote it was named the second wonder of the city, and the slope itself is often called the face of Nizhny Novgorod [5]. In 2006, local historian and UNESCO Chair professor at the Nizhny Novgorod University of Architecture and Civil Engineering Tatyana Vinogradova proposed to the regional government that documents be prepared to nominate the Volga escarpment for inclusion on the UNESCO World Heritage List [17].

Geology

The Volga Upland here is a broad stepped plateau, cut by numerous ravines and bounded to the north and east by the valley of the Volga, to the west and southwest by the valley of the Oka, and to the south and southeast by the valleys of the Kova and Rakhma rivers. The watershed separating the Kova and Rakhma basin from the Oka and Volga valleys runs along Gagarin Avenue, Bolshaya Pokrovskaya Street, Bolshaya Pecherskaya Street, and Kazanskoe Highway. In the northern part of the upland, elevations of 200–220 metres have been recorded; the river valleys cutting across the plateau are well developed, asymmetrical, and have several above-floodplain terraces [1].

The surface of Dyatlov Hills is composed of periglacial-deluvial loam deposits overlying red-coloured Permian-period rocks [4]. The landslide hazard in the upper town is linked to groundwater: permeable marls slide over impermeable clays, and their alternation is characteristic of the entire upper town's geological structure [1]. Landslides occur both on the frontal slopes of the Oka and Volga valleys and along the sides of ravines and gullies; on sun-facing ("frontal") slopes they are active, while on shaded slopes they slow down [3].

Along the base of the Oka-Volga slope, on the section from Malinovaya Gryada to Lagerny Ravine and from the Koshelevka sloboda to the eastern edge of Pechyory, a narrow strip runs known as the burlak towpath (bichevnik), separating the bedrock slope from the river [1]. On the section from Lagerny Ravine to the ski jump, the towpath is covered by an artificial filled-and-dredged terrace up to 22 meters wide, built over with structures.

Loess-like loamy soils are intensively eroded by surface water, which is why the coastal-slope territory is characterized by a dense network of ravines and gullies; the depth of erosional incision reaches 100–150 meters. The ravines of the upper town are deep, with steep thalweg gradients and a V-shaped, almost canyon-like form; they are in a stage of vertical incision. Their mouths are, as a rule, hanging and positioned several meters above the water level in the rivers. In cross-section the ravines are asymmetrical: the right-hand walls (sun-facing) are steeper than the left-hand ones (shade-facing). The distance between ravines ranges from 200 to 600 meters. Some ravines in the city center have been filled in; many are used for road descents [1] — among them Zelensky, Komsomolsky, Pochтovy, and Lagerny.

Landslides: from the destruction of Pechersky Monastery to the present day

The most famous landslide in the city's history occurred on June 18, 1597: a massive landslide completely destroyed the original Pechersky Monastery, which by the mid-16th century had housed six stone churches — twice as many as in the rest of the city. Signs of trouble appeared a week before; the monks were evacuated in advance, taking with them icons, vestments, and sacred vessels, and no one was harmed. The monastery was rebuilt higher up the river and closer to the city — this is the present-day Voznesenskiy Pecherskiy Muzhskoy Monastery — while on the former site stands the Spaso-Preobrazhanskaya Church of the Starye Pechyory sloboda [6].

The slope was already sliding when efforts to improve it began. According to accounts by Nizhny Novgorod tour guides, during the construction of the embankment in the 1830s the work was carried out by prison-gang laborers; the slope was reworked eight times, yet every spring it stubbornly slid back into the Volga. The project was rescued by contractor Pyotr Yegorovich Bugrov — a former burlak (Volga barge hauler) and future founder of a merchant dynasty — who understood that the groundwater needed a natural outlet, and his crew installed drainage [5]. Urban-planning historians also describe the Volga Slope as a kind of monument to P. Ye. Bugrov: his name is associated with the competent reinforcement of the slopes that made the development of the embankment possible [2].

Today the slopes of the upper town remain under constant monitoring. In 2014, twenty hazardous sections were counted in the upper town; hydrogeologists linked the risk to spring weather, spring floods, and rising groundwater levels, while municipal services attributed it primarily to construction on the slopes, water mains, and water towers. Residents of Pechyory reported that the slope on the bank of the Volga had "shifted" some ten meters over the course of half a century [7].

History of development

In the Middle Ages, part of the Volga escarpment belonged to the Upper Posad, within the boundaries of the Small Ostrog; according to some sources, at the junction of the present-day Verkhne-Volzhskaya Embankment and Piskunova Street stood a gatehouse tower of the ostrog, approached by two steep descents from the Volga bank. Around the mid-sixteenth century, a wooden Church of St. George was built here; in the early eighteenth century it was rebuilt in stone and became the dominant landmark of the entire slope [2].

The edge of the bank, cut through by ravines, long remained unsuitable for development: general plans from the late eighteenth and early nineteenth centuries envisioned a broad embankment road here, but until the 1830s the escarpment and hillside were occupied by kitchen gardens and outbuildings [2]. Everything changed with the "imperially commanded works" initiated after the visits of Nicholas I: a design for the embankment by the provincial architect I. E. Yefimov and engineer P. D. Gotman was approved in 1835, and by the early 1840s part of the bank's edge had been straightened and reinforced, the ravines filled in, the roadway leveled, and partly paved with cobblestones [2]. The estimated cost of the entire redevelopment program came to 12,566,776 rubles and 42.5 kopecks in silver, and the city was obliged to take out a government loan [5].

On the leveled terraces of the escarpment, between the Upper and Lower Volga embankments, a large English Garden — also known as the Alexandrovsky Garden — was laid out in a picturesque style and quickly became beloved by the townspeople. The embankment began to be lined with stone buildings "of the finest facades," and by the 1890s it was fully developed along its entire two-kilometer length; one of its ornaments was the Rukavishnikov Estate (1877, architect P. S. Boytsov, sculptor M. O. Mikeshin) [2]. The Kazansky Descent and the Georgievsky Descent led down to the Volga [2], while from Blagoveschenskaya Square an elevator — the Pokhvalinsky lift, 143 meters long with carriages holding 30 passengers — ran up the escarpment from 1896 to 1929 [19].

In the Soviet era, a viewing platform with a Chkalov Monument (1940) was laid out near the Kremlin's St. George Tower, and between 1943 and 1949 a monumental staircase was built down the escarpment to commemorate the victory at Stalingrad — the The Chkalov Staircase (architects A. A. Yakovlev, L. V. Rudnev, V. O. Munts). In 1949 the embankment's edge was enclosed by a continuous cast-iron railing designed by D. P. Silvanov; in 1958 the eastern end acquired a ski-jump trestle, and in 1968 the Chayka café was built at the point where the embankment widened most toward the terraces [2]. The Church of St. George was demolished; on its site between 1932 and 1935 the Tsentralnaya Hotel was built — later renamed Rossiya, and now the Volzhsky Otkos hotel (architects A. Z. Grinberg and M. T. Smurov) [2]. The embankment itself was known in the Soviet years as A. A. Zhdanov Embankment; its historical name was restored in the early 1990s [18].

Slogans on the slope

The high bank, visible from the river at a great distance, served in Soviet times as a platform for large inscriptions. In photographs from the 1960s taken from the water, the slogan "Communism will triumph!" — assembled from individual letters on the roof of a residential building at the edge of the slope — stands above the hillside.

Views and observation points

The city of Bor, Tolokontsevo, the railway bridge across the Volga, the Strelka, and on a clear day Balakhna — all form a panorama of the trans-Volga expanses that opens up from the Verkhne-Volzhskaya Embankment. Walking along the embankment from its bend toward Minin Square, the Kremlin's Georgievskaya Tower and the Chkalov Monument rise ahead; heading in the opposite direction, toward Sennaya, the ensemble of the Pechersky Monastery comes into view [2].

The slope itself, with its garden, is well visible when approaching the city from the Bor side; from the river, the panorama unfolds as one moves along from the deck of a river vessel; and it is also visible from the dam of the Rowing Canal at its foot [2]. The main vantage points are the Verkhne-Volzhskaya Embankment, the Chkalov Staircase, and Aleksandrovsky Garden; their panoramas are included among the protected features of the Volzhsky Otkos landmark site [2].

On the Oka slope, comparable views open up from Fedorovsky Embankment: from there, the river station, the Stroganovskaya Church, and the buildings along Rozhdestvenskaya Street are laid out in plain sight, while the slope is cut through by the Sergievsky and Uspensky ravines with their pedestrian bridges [19].

The Otkos in literature and cinema

The high Volga bank is one of the recurring images in Nizhny Novgorod literature. Maxim Gorky, in his novel Foma Gordeyev (1899), described a steamship sailing down the Volga: the left bank "stretches all the way to the edge of the sky," while the right bank rises steeply [20]. Vyacheslav Shishkov, in Ugryum-Reka, planted the Otkos in the memory of his hero: at the mention of the countess, Prokhor's mind flashes with images of the yarmarka and "the green slope of the kremlin" [21]. The poet Boris Kornilov opened a poem directly with the Otkos, and the line about the Dyatlov Hills rings through it twice [22].

The Verkhne-Volzhskaya Embankment above the Otkos has long served as a filming location. It was used for Yekaterina Voronina (1957), starring Lyudmila Khityayeva, and for Alexander Rogozhkin's Miss Millionерsha (1988) with Nikolay Karachentsov [23], and later for the television series Zlye Lyudi (2024), based on the detective novels of Nikolay Svechin: in the Rukavishnikov manor and on the embankment, its creators found the atmosphere of the late nineteenth century with no need for sets [24].

…while the right bank flung its wooded cliffs toward the sky and froze in stern repose.

— M. Gorky, Foma Gordeyev, 1899 [20]

— A countess?! — Prokhor exclaimed in astonishment, and his heart ached. Before his eyes flashed in quick succession: Nizhny Novgorod, the yarmarka, the green slope of the kremlin, the gang of thieves.

— V. Ya. Shishkov, Ugryum-Reka [21]

Modern Era

Since the 1990s, Aleksandrovsky Garden has largely fallen out of city life: overgrown paths, crumbling walkways and staircases, and deteriorating infrastructure [16]. In December 2020, a procurement was announced for the renovation of the regionally significant cultural heritage site "Nizhny Novgorod Otkos" — the slope between the Chkalov Staircase, the Nizhne-Volzhskaya Embankment, the Kazansky Descent, and the Verkhne-Volzhskaya Embankment, together with Aleksandrovsky Garden — at a cost of approximately 500 million rubles: the funds were allocated for the restoration of the outdoor bandshell, repair of staircases, a viewing platform, a sports area, illuminated arches, and lighting; the procurement was commissioned by the ANO "Tsentr 800" [15]. The project by the Wowhaus bureau, carried out on commission from the ANO "Institute for Urban Development of Nizhny Novgorod Region" (designed 2019–2020, implemented 2020–2021), covered 350,000 square meters: the garden's historic stage was restored, and arches, gazebos, outdoor workout areas, and observation platforms were added [16].

The Chkalov Staircase was reopened after restoration on August 1, 2021 — the same date it had originally opened in 1949. According to the regional government, it has 442 steps and was long considered the longest staircase in the country [14]. Landslide-prevention work on the Kremlin slopes, begun following a 2020 landslide, continued into 2024 [11], while a dispute over payment for the work was still being heard in court as late as the summer of 2026 [12].
