Ostankino Tower

• 1. Introduction

  ›

  The Ostankino Tower rises 540.1 meters above Moscow, making it the tallest free-standing structure in all of Europe. It was built to mark a specific anniversary: the 50th year since the October Revolution. And when it opened in 1967, it did not just dominate the Moscow skyline. It became the tallest free-standing structure in the world, surpassing even the Empire State Building in New York City. That record held for seven years.

  But the tower is more than a feat of engineering ambition. It carries a Soviet dream about broadcasting, about reach, about who gets to speak to whom. At the time construction finished, roughly 10 million people lived within its transmitter coverage area. By 2014, that number had grown to over 15 million. What drove the push to build something so tall, so fast, and with so little underground foundation? And what happened the night a fire nearly brought it all down?

• 2. A Dream in Concrete

  ›

  Before Ostankino, Moscow relied on a tower designed by Vladimir Shukhov in 1922 to broadcast its signals. That older structure, a steel lattice known as the "wicker" tower on Shabolovka Street, was celebrated in its time as an extraordinary piece of engineering. But by the 1950s, it had reached the end of its useful life. Originally built for radio, it had been pressed into television service starting in the late 1930s, a purpose its designers never imagined.

  The competition to replace it was won initially by the Kyiv Design Institute for steel structures, which proposed an openwork metal tower in the spirit of the Eiffel Tower in Paris. The architects assigned to develop that design were unenthusiastic. Nikolai Nikitin, a member of the competition committee and a specialist in reinforced concrete and metal structures, rejected the approach outright. He found the lattice metal design unappealing and argued for concrete instead. His case rested on a precedent: a similar structure in Stuttgart, completed in 1956, just two years before he made the pitch.

  Nikitin later said he conceived the design overnight. The cone-shaped foundation, he claimed, came to him in a dream, inspired by the upside-down form of a lilium flower, known for its robust petals and sturdy stem. But there were other influences, acknowledged or not. Scientist Yuri Kondratyuk had envisioned a thin hollow concrete tower reinforced with steel cables for a wind farm on Mount Ai-Petri in Crimea back in the 1930s. Kondratyuk designed a 165-meter version of this idea. That project was never finished, but the concept stayed in circulation. There is also a striking resemblance between the Ostankino base and a 1932 project called the "Monument of the Banner," presented by architect Pier Luigi Nervi in Rome. Whether Nikitin knew of Nervi's sketches remains uncertain. The lattice metal design that lost the competition was eventually built as the Kyiv TV Tower, shortened by nearly 30 percent so it would not rival Ostankino's height.

• 3. Building Against Doubt

  ›

  Nikolai Nikitin proposed a 540-meter concrete structure resting on a foundation that reached only 4.6 meters underground. Many of his colleagues were alarmed. They urged him to reinforce the base with 40-meter piles and even wrote collective letters calling for construction to be halted.

  Nikitin's answer to instability was counterintuitive. He relied on a shifted center of gravity, which works the way a roly-poly toy does: the structure can lean but returns upright. During construction, the maximum deflection of the spire reached approximately 12 meters. That movement was not evidence of failure; it was the design at work. To guard against corrosion of the internal steel cables over time, engineers coated them with gun oil, a petroleum-based substance made thicker by combining it with petrolatum and ceresin. A total of 150 such cables were installed inside the structure.

  Construction began in 1959, and the scale of the operation required building an entire support town on site, complete with a boiler house, a concrete plant, and a mechanical workshop. Workers raised the tower trunk using a self-lifting crane, and helicopters were brought in to install the antenna at the top. Architects Leonid Batalov and Dmitry Burdin shaped the exterior, adding arches between the supports, a glazed cylinder below the trunk to house broadcasting studios, and illuminator windows in the upper cone that gave the whole structure the silhouette of a rocket. At heights between 325 and 360 meters, a structure equivalent to a ten-story building was inserted into the tower, containing equipment rooms, an observation deck, and a revolving restaurant spread across three floors.

• 4. The Seventh Sky

  ›

  On the 7th of November 1967, Soviet leaders Nikita Podgorny, Alexei Kosygin, and Leonid Brezhnev visited the restaurant inside the newly opened tower. The establishment they dined in was called "Seventh Sky," and it occupied three halls named Bronze, Silver, and Golden, spread across floors ranging from 328 to 334 meters above the ground.

  Each hall held 24 four-seat tables arranged in a circle near panoramic windows, with a radius of 9.2 meters per hall. The total floor area of all three halls was 600 square meters. Reservations were required because each hall held a maximum of 80 people at once. Since opening in 1967, the restaurant was considered the highest dining establishment in the Soviet Union and one of the most expensive. In 1987, the cheapest hall, the Bronze, charged 7 rubles for a daytime visit, and diners had no choice of dishes. What drew visitors beyond the food was the movement: the circular rooms completed one full rotation every forty minutes.

  Over the 33 years the restaurant operated before the fire of 2000, roughly 10 million people visited. The observation deck alongside it drew the same total across the same period. The experience of standing above Moscow, in a room slowly turning, became one of the defining attractions of the Soviet capital for tourists and citizens alike. That unbroken run of 33 years would end on a single afternoon in August.

• 5. Fire at 460 Meters

  ›

  At around 3 in the afternoon on the 27th of August 2000, a fire broke out at a height of 460 meters inside the Ostankino Tower. That placed the origin roughly 98 meters above the observation platform and the Seventh Sky restaurant. The flames spread quickly through nearby areas of the structure, and it took firefighters and emergency personnel until the following evening to extinguish them.

  Of the 150 steel cables inside the tower, only 19 survived intact. The fire safety systems inside the tower had failed, which forced firefighters to carry heavy chemical extinguishers up the tower on foot. Temporary asbestos firewalls were erected at a height of 70 meters to slow the spread. All visitors and staff were evacuated within 90 minutes of the fire starting. Three people died: a firefighter and a lift operator whose elevator cabin fell to ground level, and a third individual in another cabin. Three people were present in that second cabin, and none of them survived.

  The consequences extended far beyond the structure. All of Moscow lost television reception. Radio signals were disrupted. Most channels went dark for months while repairs were made, though the state-owned RTR channel managed to restore a partial signal to some districts quickly. The privately owned NTV station was the only broadcaster to avoid significant disruption. The fire also tilted the upper spire slightly, triggering fears that the tower might collapse. Engineers inspected the structure and concluded there was no immediate risk, but the damage was severe and the rebuild would take years.

  Russian President Vladimir Putin addressed the fire publicly, linking it to a broader pattern. That same month, an explosion at Pushkinskaya Metro Station in Moscow had killed 12 people and injured 150, and the submarine Kursk had sunk in the Barents Sea with 118 people aboard. Putin described the tower fire as a sign of the state of Russia's vital infrastructure and called on the country not to ignore the larger problems it represented.

• 6. Reconstruction and Return

  ›

  The tower remained closed to visitors for eight years after the 2000 fire. The first new elevators, built by the German company ThyssenKrupp, were tested and put into service on the 25th of March 2005. Those elevators travel at 6 meters per second. The full set of four high-speed ThyssenKrupp elevators was not completely installed until the 21st of November 2005, with a fourth high-speed unit entering service in December 2006.

  The observation deck reopened for pilot tours on the 27th of March 2008, and the full reconstruction of the deck was complete by January of that year. The restaurant was a different matter. It took 16 years from the fire for the Seventh Sky complex to reopen in any form. The coffee shop and cafe levels came back in 2016, and the restaurant hall followed in 2017, only to close again temporarily in 2020 due to pandemic restrictions.

  The rebuilt restaurant bears little resemblance to what stood there before. The interiors are entirely different, and the dining experience was overhauled along with the physical space. On the 21st of July 2018, the tower hosted a stair race drawing athletes from 12 countries. Twenty-eight competitors ran up the narrow spiral staircase to the 337-meter mark. German athlete Christian Riedl won in 9 minutes and 51 seconds. American Cynthia Harris took the women's title in 12 minutes and 15 seconds. The race brought a kind of athletic spectacle to a structure still bearing the scars of the worst disaster in its history.

• 7. The Flag at the Top

  ›

  On the 27th of April 1967, a flag of the USSR was placed at the very top of the Ostankino Tower, giving it the unofficial title of the world's tallest flagpole for many years. The flag was replaced twice a year, on May Day and on the 7th of November. The original plan called for a flag measuring 50 by 20 meters, but that was scaled back to 5 by 2 meters because engineers calculated the larger size would impose too much load from wind.

  In 1991, the Soviet flag came down and the top of the tower stayed bare for more than 17 years. On the 12th of June 2009, which is celebrated in Russia as the Day of Russia, a new Russian flag was hoisted in its place. The flag made specifically for the tower was sewn in the city of Vladimir using reinforced fabric. The old Soviet flag that was lowered in December 1991 is now held in the tower's museum, preserved as an artifact of the era the tower was built to serve.
