At the beginning of the 20th century, many Finns became active in the cause of civilization, which was supported by religious, political and non-committal popular movements. One such was born in Turku in 1917, when there was a will to establish a Christian college in Southwest Finland. On 21 October 1917, a public meeting was held, which led to the founding of Turku Kansanopisto Oy. However, the project faced setbacks and finally the board of the Southwest Finland Christian People's College decided to establish its own college in the fall of 1925.
Due to the need for space, the Turku Christian People's College already acquired its own building at Sirkkalankatu 40 on January 12, 1926. In the fall, the school board had time to deny the college state aid in its statement, and after the battles, the college's dedication ceremony was held on December 15, 1926.
The college went through many phases during the 20th century. Among other things, during the time of its leader Olavi Kares (1930–1960), it applied to be part of the group of awakening or charter schools, and during the winter war on January 12, 1940, a bomb badly destroyed the college building. However, already in the same fall, the college accepted a record number of students.
The educational need of the baby boomers and the rapid change in society after the war created the need to reassess the college's future boldly. In 1965, the college acquired approximately 4.5 ha of land from the city of Turku, Prusi estate, near Linnamäki. The plans for the new college were completed in 1971.
The construction plan was implemented by Pekka Pitkänen Architects' Office and construction work on the new college building began in June 1972. The construction work was completed in the fall of 1973 (brush-raising ceremony on August 31 and dedication on December 9), three months later than planned. Pitkäsen's modern architecture can be seen in flat roofs, shapes and the dialogue of concrete, metal and strong colors. At the time of its completion, the building was very modern in design.
