The greystone church in Parainen was built in the 15th century (probably in 1440-1460) and is dedicated to St. Simon. The western part of the Agricola-chapel is the eldest component of the church, today a museum. On the churchyard is located the chapel of bishop Tengström, Finland's first archbishop (erected in 1819). The interior of the church is covered with several coat of arms. The rarest one is dedicated to pope Innocentius III.
National Board of Antiquities has named the church and the surrounding Vanha Malmi old town as national built heritage.
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.
