He notes that many toponyms with the word pyhä have referred to remote locations, with the island of Pyhämaa being far away from the early population centers of Untamala (Laitila) and Kalanti.

Pyhämaa became separate again in 1908, while Rohdainen was renamed Pyhäranta, a name that was likely invented by the skipper Kustaa Aaltonen from the village of Hirslahti.

Another part of Kalanti was transferred to Pyhämaa in 1942, including Raulio and Torlahti on the mainland.

The modern shape of the church is the result of a renovation done in 1908, in which the top of the bell tower was changed.
