Nousiainen, 25km north of Turku, makes a good day trip for the Nousiainen church . It’s a noteworthy medieval church because it’s the first resting place of St Henry, an Englishman and Swedish-consecrated bishop who was the first to bring Christianity to the Finns (with a little accompanying light war) in the mid 12th century. His bones were taken to Turku Cathedral in the 13th century. The current church post-dates this, having been largely built in the 14th century and restored in the 1960s.
