Although archaeological findings in the area date back to the Stone Age, the town of Turku was founded in the 13th century. Its name originated from an Old East Slavic word, tǔrgǔ, meaning "market place". The history of Turku is often started from the letter Pope Gregorius IX wrote, dated January the 23rd 1229. The letter granted a permission to transfer the Diocese of Finland to a better place, probably meaning from Nousiainen to Koroinen.
The Cathedral of Turku was consecrated in 1300, and together with Turku Castle and the Dominican monastery (founded in 1249), established the city as the most important location in medieval Finland.

Kuusisto Castle was a medieval castle on an island of Kuusisto in Kaarina. The castle was probably built in the early 14th century, although the site seems to have been bishop's residence already in the 1290s.
The castle was ordered to be demolished during the Protestant Reformation in 1528 by the king Gustav I of Sweden. Excavation and reconstruction work on the remaining ruins began in 1891.
Also Pietari Särkilahti was included in the story. He was a Finnish student of Martin Luther and one of the early pioneers of teaching science in Finnish language. He spread the idea of the religious reformation eagerly.
