The Trinity Monastery of St. Jonas (Ukrainian: Свято-Троїцький Іонинський чоловічий монастир, romanized:Sviato-Troitskyi Ionynskyi cholovichyi monastyr; Russian: Свято-Троицкий Ионинский монастырь) is a Ukrainian Orthodox monastery in the Kyivan neighbourhood of Zvirynets, a short distance from the medieval Vydubychi Monastery.
It was Jonas, a Vydubychi hegumen, who founded this monastery in 1864. Princess Vasilchikov, the widow of Kyiv's Governor General, decided to support the undertaking and presented her dacha to the brethren.[1] It was on these grounds that the katholikon was constructed. The monastery's bell tower, at 110 meters, was to be the tallest in the Orthodox world.[2] Its construction was halted due to the outbreak of World War I. As many as 800 monks resided there at the time.
