The Greek Catholic Cathedral of St John the Baptist in Przemyśl serves as the mother church of the Ukrainian Greek Catholic Archeparchy of Peremyshl-Warsaw.
The church was built in the 17th century by the Jesuit order and dedicated to St. Ignatius. After Przemyśl fell under Austrian rule and the suppression of the order in 1773 it slowly fell into ruins and in 1820 was closed by Austrians and turned into a storehouse. With the gradual democratization of region in the second half of the 19th century plans appeared to restore the church, finally carried out in 1903 and in 1904 the former Jesuit church was reconsecrated in 1904 as Sacred Heart of Jesus. After World War II it served as a garrison church and also offered a weekly Mass in the Byzantine Rite for Ukrainian Catholics whose church had been closed by the communist government.
In 1991 the church was subject of a controversy, when the Roman Catholic Church (with personal oversight by pope John Paul II) decided to donate the building to the Greek Catholic population in Przemyśl, to serve as the cathedral of the Archeparchy of Peremyshl-Warsaw in place of the Carmelite Church, which after World War II has returned to the Carmelites. After this decision, local Polish nationalists blockaded the entrance to the Greek Catholics and organized a hunger strike. After several weeks of debate and negotiation they desisted.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
