The Orthodox Church Museum, established in Kuopio in 1957, derives from the Collection of Ancient Objects founded at the Monastery of Valamo in 1911. Most of the exhibits, which consist mainly of icons, sacred objects and liturgical textiles, are from the monasteries and congregations of Karelia: a region in southeast Finland that was partially ceded to the Soviet Union in connection with the Second World War. Objects in the museum are mainly from the 18th and 19th centuries.
In addition to the permanent exhibitions, the museum offers yearly seasonal exhibitions. These theme-based exhibitions are aimed to introduce the variety of ecclesiastical art of eastern Christian Church. The virtual exhibition is built in accordance to the physical frames of the museum building: icons and sacred objects are displayed upstairs, liturgical textiles downstairs.
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.
