[1] The inhabitants of Kakskerta, Satava and Kulho were permitted to construct a chapel in 1693, but one was not built.

In 1909, the inhabitants of Hirvensalo, then part of Maaria, pleaded the Finnish government to transfer the island to the Kakskerta municipality, which was opposed by the municipal government of Maaria.
