Back in the 16th century, Vilnius Diocese records of church visitations mentioned the Church of Dusmenys, but the Catholic church was closed as the Reformation spread. In 1667, the Chancellor of the Grand Duchy of Lithuania, Kristupas Zigmantas Pacas donated Dusmenys Manor to Pažaislis Camaldolese Monastery. In 1820, the Camaldolese monks built the present wooden church in the middle of the old cemetery. The church had two turrets and four altars. In 1883-1885, the churchyard was fenced with a brick fence covered with wood shingles, and a belfry was built. In 1904, the pastor of Dusmenys, the book smuggler Stanislavas Šlamas initiated the invitation of the organist Jonas Petrauskas, the father of the famous Mikas and Cypriot Petrauskas. Together with his sons and other musicians, Jonas Petrauskas created Dusmenys Church Orchestra. In 1937, Mikas Petrauskas was buried in the churchyard next to his parents. The remains of Stanislavas Smolinskas (1889-1975), the longtime pastor and dean of the church, were also buried in the churchyard. In 1965-1967, the church was renovated thanks to the priest Marijonas Petkevičius.
