St. Olaf’s Church: possibly the tallest building on Earth, then a Soviet KGB listening post
A Tallinn, in Estonia, la Chiesa di Sant’Olav è menzionata per la prima volta in una carta del 1267 della regina danese Margherita di Danimarca, dedicata a Sant’Olav II Haraldsson, re norvegese canonizzato e patrono dei naviganti, e fu per secoli la chiesa centrale della comunità mercantile scandinava, in particolare norvegese, di Tallinn. Dopo una ricostruzione databile intorno al 1549, la guglia raggiunse un’altezza riportata di circa 159 metri, rendendola, secondo una tradizione storica ampiamente ripetuta ma di fatto non del tutto verificabile, forse la struttura più alta al mondo dal 1549 al 1625; la stessa Wikipedia segnala che la cifra deriva da una fonte d’epoca che parla di “84 tese”, una misura la cui conversione esatta in metri resta incerta a seconda dell’unità di riferimento utilizzata. La torre fu colpita da fulmini circa dieci volte nel corso della sua storia, e la chiesa brucia completamente almeno tre volte: nel 1625, quando la guglia da record fu distrutta e la ricostruzione si protrasse fino al 1651, e nel 1820, quando un fulmine distrusse cupola e pinnacoli, seguito da circa vent’anni di ricostruzione che fissò l’edificio all’altezza attuale per motivi di stabilità; incendi minori, rapidamente domati, sono documentati anche nel Sei e Settecento. Una nota leggenda locale narra di un misterioso costruttore di nome Olev, che avrebbe innalzato la guglia sotto una maledizione secondo cui chi l’avesse completata sarebbe morto: chiamato per nome dagli abitanti proprio mentre poneva l’ultimo elemento, sarebbe caduto per lo spavento, e dalla sua bocca, secondo il racconto, sarebbero usciti un rospo e un serpente, simbolo di possessione demoniaca; un volto scolpito in pietra sull’edificio è popolarmente identificato con lui, ma si tratta di folclore, non di fatto storico. Dal 1944 al 1991, durante l’occupazione sovietica dell’Estonia, il KGB estone utilizzò la torre come punto di sorveglianza radio e disturbo delle trasmissioni straniere, in particolare finlandesi, con antenne collegate al quartier generale del KGB in via Pagari, un uso che secondo alcune fonti potrebbe paradossalmente aver contribuito a preservare l’edificio. Oggi la guglia raggiunge circa 123-124 metri, più bassa del picco storico, e la chiesa è utilizzata dalla congregazione battista cristiana estone, con una piattaforma panoramica pubblica a circa 60 metri, raggiungibile tramite una stretta scala a chiocciola.
About St. Olaf’s Church
In Tallinn, Estonia, St. Olaf’s Church is first documented in a 1267 charter by Danish Queen Margaret of Denmark, dedicated to Saint Olaf II Haraldsson, the canonized Norwegian king and patron saint of seafarers, and served for centuries as the central church of Tallinn’s Scandinavian, particularly Norwegian, merchant community. After a rebuild datable to around 1549, the spire reportedly reached about 159 metres, making it, according to a widely repeated but not entirely verifiable historical tradition, possibly the tallest structure in the world from 1549 to 1625; Wikipedia itself notes the figure derives from a period source describing the tower as “84 fathoms,” a unit whose exact conversion to metres remains uncertain depending on which fathom standard was used. The tower was struck by lightning roughly ten times over its history, and the church burned down completely at least three times: in 1625, when the record-height spire was destroyed and reconstruction dragged on until 1651, and in 1820, when lightning destroyed the cupola and turrets, followed by roughly two decades of rebuilding that fixed the structure at its present height for stability; smaller, quickly extinguished fires are also documented across the 17th and 18th centuries. A well-known local legend tells of a mysterious builder named Olev, said to have raised the spire under a curse that whoever finished it would die: called out by name by the townspeople just as he placed the final piece, he fell to his death in fright, and a toad and a snake reportedly emerged from his mouth, symbolizing demonic possession; a carved stone face on the building is popularly identified with him, though this remains folklore, not documented history. From 1944 to 1991, during the Soviet occupation of Estonia, the Estonian KGB used the tower as a radio surveillance and jamming post for foreign broadcasts, particularly Finnish ones, with antennas connected to KGB headquarters on Pagari Street, a use some sources suggest may have paradoxically helped preserve the building. Today the spire reaches roughly 123-124 metres, lower than its historic peak, and the church is used by the Estonian Christian Baptist congregation, with a public viewing platform at around 60 metres reached by a narrow spiral staircase.

History
Few churches anywhere combine a genuinely disputed claim to having once been the tallest building on Earth with a documented Cold War role as a KGB listening post, but St. Olaf’s holds both distinctions within a single continuous structure. Its repeated destruction by lightning and fire across five centuries, followed each time by rebuilding, mirrors the church’s broader role as a landmark that successive eras of Tallinn’s history — Hanseatic trade, imperial rule, Soviet occupation, and independence — each left their mark on.
What you see
A tall Gothic spire, rebuilt after repeated fires and now standing at roughly 123-124 metres, rises above Tallinn’s Old Town, its narrow spiral staircase leading to a viewing platform at around 60 metres. A carved stone face on the exterior is popularly linked to the legend of Olev, the spire’s ill-fated builder, while the tower’s Soviet-era antenna mounts, now removed, once served a very different purpose.
