Kerttu Tamminen

She graduated from University of Jyväskylä and was hired as a designer and architect for the reconstruction of the Kirkkopuisto. The park and the square and the streets around it were completed in 1935.^[2]

Originally, the current Kirkkopuisto was a large market square. Historical documents indicate that in 1837, in the middle of this large market, a place was considered for the construction of a church, which was completed only in 1880 after several stages. In 1931, Pauli E. Blomstedt and Kerttu Tamminen were invited to present proposals for the future expression of Kirkkopuisto.^{[3][failed verification][1]}
