The brick-made Joensuu Church was built in 1903 and designed by a Finnish church architect Josef Stenbäck. The church is in the Gothic Revival style, but it also has some features of Jugendstil. The high tower located in the southeast corner is the bell tower and in the lower southwest tower is the organ. It was built in 1969 by Organ Factory of Kangasala and has 36 stops. The church has 1000 seats. On the altar is a painting The Crucifixion of Jesus, made by Ilmari Launis in 1910.
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.
