 Even at the time of the building of Petäjävesi church, with its "cross plan", more complex ground plans had already existed in Finland, but in later years the ground plans would become even more complex.The first so-called "double cross plan" in Finland was probably the Ulrika Eleonora church in Hamina (1731, burnt down 1742), built under the direction of master builder Henrik Schultz.It was then replaced by a somewhat similar church, the Church of Elisabet in Hamina (1748–51, destroyed 1821), built under the direction of Arvi Junkkarinen.
