Koroinen (Finnish:[ˈkoroi̯nen]; Korois in Swedish) is a district in the Koroinen ward of the city of Turku, in Finland. It is located to the north of the city centre, across the river Aura from the Turku Student Village.
Koroinen is mostly non-built-up area, consisting largely of recreational area. The current (as of 2016[update]) population of the district is 15.[1]
The church in Koroinen was later destroyed by the Victual Brothers in 1396. There is a white, wooden memorial cross and some stone foundations still remaining on site.
