The island of Kuusisto has participated in the heartbeat of the world since the 14th century. The bishop's castle and mansions built on the eastern end of the island were part of the country's administrative centers in the Middle Ages. During the Reformation in the 16th century, the castle was dismantled, but the mansion became the estate of Turku Castle and later the official residence of the commander of the Finnish military.

In the 18th century, the Great Northern War also hit Kuusisto. The island experienced the strains of three wars and two Russian occupations like the rest of Finland. Still, the people of Kuusisto wanted to build their own new church.

Kuusisto's chapel congregation was founded in 1653. After that, the peasants built a wooden church on the hill. Its shape is unknown, but it is known to have fallen into disrepair in the late 18th century.

The current church is from 1792. It was renovated in neo-Gothic style between 1899 and 1900. The building was restored in 1973–1974 under the direction of architect Pekka Pitkänen under the supervision of the Finnish Heritage Agency.
