Koroinen
Koroinen [ 'kɔrɔi̯nɛn ] ( Swedish. Korois ) is a district of the Finnish city of Turku . It is located north of the city center on a headland at the confluence of the Aurajoki and Vähäjoki rivers . The Koroinen area is largely undeveloped, so the district has only 26 inhabitants (2004).
In the Middle Ages Koroinen was the center of Finnish church administration: in 1229 the seat of the bishop of Finland was moved from Nousiainen to Koroinen, as there was an important trading post on the lower reaches of the Aurajoki. In the 1230s the wooden Koroinen Episcopal Church and a residence for the bishop were built. In the middle of the 13th century, the first bishop's church, which was destroyed by fire, was replaced by a new, larger wooden church. It is possible that a stone choir was added at the time of Bishop Catillus (1266–1286) . In the vicinity of the church there were two other stone buildings. It could have been a fortified tower and the bishop's palace, but the exact function of the building is just as little proven as its age.
When the level of the Aurajoki sank due to the land uplift and the river was no longer navigable up to the level of Koroinen, the trading center relocated to the location of today's city center of Turku just under two kilometers downstream. After the completion of the Turku Cathedral , the bishopric was also moved to Turku at the end of the 13th century. The church of Koroinen initially remained, but was later abandoned (possibly in the 15th century) and fell into complete disrepair. In 1898–1902 the first systematic archaeological excavations were carried out in Koroinen, during which the foundations of the medieval stone buildings were exposed.
