The Church of Our Holy Redeemer was built between 1834 and 1836 according to the plans of architect Karl Rösner. Originally, it served as the church of the Redemptoristine Nuns; the convent building was added later. It was the first project of this architect in Vienna, who decisively influenced the development of the Historicism style in the city. Initially, the church was built in the Neo-Renaissance style and subsequently rebuilt into its present form.
In 1908, the church and the convent became the property of the Society of Saint Method, which also had a meeting hall built for its members.
Since then, the church has been used by the Czech diaspora in Vienna. In the beginning, the Church ministry was being provided by the Eucharistian Order. In 1922, the administration of the church came under the new congregation of Consoler Brothers of Gethsemane.
The church consists of the main nave, two aisles and the chapel of Holy Mary, which is built in Neo-Baroque style. During the Second World War, a bomb damaged the church and demolished the main altarpiece. The current altarpiece consists of a painting of the Divine Heart of Jesus with angels and patrons of Czech and Moravian people.
The side altarpieces are dedicated to the following saints: Saint Joseph, the Pieta, Francis of Assisi, Agnes of Bohemia, Alphonsus Liguori, the Infant Jesus of Prague, Santa Anna, Jesus in the garden Gethsemane and the Blessed Sister Restituta Kafka
Blessed Sister Restituta Kafka is a very important figure in the history of the Czech diaspora in Vienna. She was the first Viennese martyr, however with Czech ancestry. She was born as Helena Kafková in Brno, where she spent the first years of her life. Later, she moved to Vienna with her parents. In 1914, she became a member of the Franciscan Congregation of Christian Charity and was given the name Maria Restituta. She worked as a nurse until 1942 when she was imprisoned by the Gestapo. She was sentenced to death for “enemy favoring and preparing for high treason” and executed on 30th March 1943. Shortly after she had been condemned to death, she wrote: “I forgive those who were involved in my sentencing from the bottom of my heart … Please, don’t blame anybody and forgive them from the bottom of your heart, as I do.”
Her life provided an example to other people who were imprisoned with her and as a consequence some of them became members of the Catholic Church. In 1998, Pope John Paul II beatified her.
