Yli-Ii is probably best known from a pre-historical museum called Kierikkikeskus.
Yli-Maaria (Övre S:t Marie in Swedish), a district of Turku named after the latter.
The altarpiece of the church, painted by Eero Järnefelt and rescued from the fire that destroyed the previous church, features Pietari käy yli veden ("Peter on the water") and below it Jonas Heiska's painting Kristus ja lampaita ("Christ and the sheep.")
